This book covers all the essential topics in Java development. It is not just for beginners; experienced programmers can also review the chapters for a quick reference. It can be used both as an introductory programming class using Java and also as upper level class that covers GUI programming using Java.

Content Accuracy rating: 5

I haven't seen any example with an obvious error. Having the source code available online for practice is a nice feature.

Relevance/Longevity rating: 5

Java is updated regularly. Although it is hard to keep up with the updates, I still think the book is using a fairly new version of Java. The reader will not miss much with the used version and if they want to learn the latest version, they can do it easily.

Clarity rating: 4

The book is easy to follow and flows naturally from beginning to end. It introduces various concepts not generally seen in a programming language book, such as section 8.5, Analysis of Algorithms. While I appreciate the author's initiative, the example used in the first paragraph is rather exaggerated/dramatic ("..correct answer after ten thousand years...").

Consistency rating: 5

The book uses consistent terminology throughout. All the codes/code segments were formatted using the same style. While the authors provided an explanation for using the term "subroutine" in chapter 4, I personally still think using the name "method" would be more beneficial for the reader.

Modularity rating: 5

The book's modularity enables instructors of introductory Java programming courses to teach with ease. Instructors have the flexibility to select essential chapters while reserving more advanced topics for students at higher levels of proficiency.

Organization/Structure/Flow rating: 5

The book is organized in a logical fashion.

Interface rating: 5

Navigating the book is incredibly straightforward. The website provides various options such as online access, PDF downloads, and other convenient methods to explore its contents.

Grammatical Errors rating: 5

I did not notice any obvious grammatical errors in my reading.

Cultural Relevance rating: 5

While, I do not see examples of the inclusion of various races, ethnicities, and backgrounds. The most important thing is I also did not see any insensitive, or offensive content either. For the subject matter, I believe the book is perfectly fine.

The book covers all parts needed for a freshman course. It is can be used as one semester or one year book for Java programming.

The syntax explanations are precise. The Java examples are error free.

Relevance/Longevity rating: 4

The book doesn't use the most recent version of Java Environment. However, I do not think that is a problem. Beginners do not need the up-to-date new syntax to do well in a problem solving course.

Clarity rating: 5

The book is very concise, and easy to follow.

The book is very well organized in style. Similar formats are used from the beginning to the end.

Modularity rating: 4

The book follows the standard modularity for a first programming course. It begins with an introduction to computation, then followed by Java basics. It is a great book for a fast paced course. However, for some schools with a slow paced programming course, covering more basic programming skills and more examples could improve the learning experience.

Organization/Structure/Flow rating: 4

I feel the book should cover the basics in more details and more examples. The order of the some topics are not conventional. For example, "if" structure is covered after the looping structures; and programming environment is in the last section of Chapter 2, not in the first section.

The book is very easy to use. The website offers online, PDF, and other ways to navigate.

I do not see any grammatical errors.

Cultural Relevance rating: 4

The book doesn't not make use of a lot of examples relevant to races, ethnicity, or diversity. However, I did not see any culturally insensitive, or offensive content.

I'd recommend the book for any one looking for a first year programming course.

This book is quite comprehensive and it provides all foundational topics for beginners to learn the Java programming language. In addition, it offers a nice overview of Java programming environments and includes chapters on graphical user interfaces and programming with multi-threading. The book is suitable for a typical first programming course in Java and some of the book’s material can also be used for a subsequent programming course.

I did not find any technical errors or inaccuracies in the book.

The current 8th edition of the book is based on Java 8 and it uses JavaFX for GUI programming, so the book’s content is quite up-to-date. Of course, as more features are periodically added to the Java language, the book will need to be revised accordingly.

The book is extremely well-written and easy to follow. In fact, the author uses a conversational writing style and provides clear explanations of concepts and principles throughout the book. All of these make it a good text book for beginners.

The author uses consistent terminology internally. But the term “subroutine” introduced in the book would not be consistent with other Java sources including Oracle’s Java Documentation where the term “method” is used. This external term inconsistency may cause some confusions to readers.

The book is generally modular. One could cluster and rearrange some of its chapters or sections to fit an intro to Java class. However, the book’s modularity could be further enhanced by re-organizing its coverage of some topics. For instance, it would be good to separate the section on recursion from linked data structures and to consider expanding it to a chapter because the recursion concept and recursive algorithms are usually difficult to comprehend for many beginners.

The author does a good job presenting the material in a logical manner. The book starts basic language constructs and then covers methods, program design, classes, arrays and some more advanced topics. At the end of each chapter, it also includes programming exercises and quizzes. One suggestion I have for book’s organization is to delay the coverage of some class related topics including inheritance, polymorphism and interfaces to a later chapter. In addition, the coverage on data structures (stacks, queues and binary trees) may be expanded so the book could also be used in a second programming course in Java.

Interface rating: 4

The book’s interface is good and it is quite easy to navigate all book components. However, I feel the interface could be improved by adding a glossary and also an index.

This is a very well-edited book.

All examples and exercises from the book are very good and they are not culturally insensitive.

Overall, this is a great book for introducing Java programming. It has a very decent coverage of all important foundational topics and provides clear explanations and nice examples and exercises. Plus, it is freely accessible.

I will definitely consider using the book in some of my future classes.

The book covers all important and necessary topics for beginners in 13 chapters. read more

The book covers all important and necessary topics for beginners in 13 chapters.

The content is very accurate but here's minor things: 1. On page 14, the word "but" was typed twice (...but but has recently been removed...) 2. In section 10.1.4, the abbreviation for Java Collection Framework should be JCF not JFC.

Content is very fresh with a full of good examples and exercises. The previous version describes Swing libraries for the graphical user interface but the current version describes the up-to-date JavaFX.

The text was written with very easy words and explains concepts clearly with appropriate examples and pictures.

The text has a very good flow with a consistent jargon and framework. For example, in section 3.8, the concept of Arrays is introduced and explained later in detail in chapter 7. Also, the GUI programming is introduced in section 3.9 as an appetizer and described fully in chapter 6 and 13 with consistency.

The text is consisted of 13 chapters and many sub sections to facilitate any instructor/user to reconstruct/reorganize the content without any difficulties.

The essential topics of Java programming are organized in a way for beginners to read and study easily.

Any interface issues are found. The PDF file that can be downloaded from the open book site provides bookmark links to specific topics of interest, and the table of contents are hyperlinked. Also, all of the name of example code listed in the text have a link to actual code.

No grammatical errors are found.

The text is full of good examples and exercises without having any bias culturally and ethnically.

The introduction to the Conway’s Game of Life and the Checkers in chapter 7, and the Towers of Hanoi and the Blob Counting in chapter 8 are very useful examples for students who are interested in game programming. Also, 3 network programming examples (a simple chat room, a networked Tic-tac-toe game, and a networked Poker game) in section 12.5 could attract a lot of student's attention.

In section 6.1.3, when a BorderPane is explained, it would be good to show a picture of a BorderPane of the 5 section as shown in section 6.5.2 or place a link to that section.

This textbook is comprehensive. It covers a significant amount of material in a well-thought out and logical manner. The text starts with basic programming concepts introducing variables, types and input and output. The author covers the basics of a variety of programming environments including Eclipse, NetBeans, and the command line environment. The next section introduces control structures, exception handling, and introduces arrays and GUI programming. The early introduction of arrays and GUI program is a nice feature, allow students to add address slightly more complex problems. The book introduces objects and classes late, allowing introductory students to focus on syntax and basic problem solving before adding objects. I believe the text is well suited to a two-semester introductory sequence, or an upper level Software Design Course. The text includes quizzes at the end of each chapter, as well as programming exercises.

I did not see any technical errors or inaccuracies in the book.

The book uses the Swing library used to build GUI applications. Swing has been replaced with JavaFX. Swing is still widely used and okay for an introductory courses; the text should be updated to cover JavaFX.

The author uses an easy to read, conversational writing style and provides very thorough explanations. The flow is very logical, with sections building on the prior section.

The author uses consistent, and for the most part, modern terminology. The use of “subroutine” can be a confusing to students. The more correct term “methods” is also used and it’s not clear why “subroutines” is introduced. I appreciate the use of JavaDoc.

The text is as modular, and the order that the modules are introduced in is very logical. It is possible to re-order the modules to match your preferences for introducing specific topics.

I like the organization of the book for an introductory course, and for a course on software design. approach. Objects and classes are covered in chapter five, after the basic programming building blocks such as control structures and methods have been covered. This allows you to choose the depth that you cover topics, going slower in an introductory class, but faster in a course on Software design. I would recommend moving some sections around. I like to introduce arrays early, and I defer exceptions until a bit later.

I did not find any interface issues. The text includes PDF links in the table of contents, and also when the text makes a reference to another section. The author also includes links to the full code examples on the book's web site. Figures are easy to read and high resolution.

The text is well edited. I found a very small number of spelling or grammatical errors in the book. The book is “cleaner” that many professional edited textbooks.

I didn't notice any instances of the text being culturally insensitive. It is difficult to always find neutral examples or references. The sample problems are appropriate.

This is one of the best Java programming texts that I have reviewed. I am currently using a different text and plan to switch to this text next semester. It is very detailed. The author provides explanations of the core concepts and provides great examples. The modular approach allows it to be used in an introductory CS class, with Java as a first language; and in a software design class focusing on object-oriented design.

This textbook is remarkably comprehensive. It covers a tremendous amount of material, including nearly every facet of the Java programming language (such as anonymous inner classes, lambdas, variable arity methods etc.). It also includes a chapter covering basic data structures such as lists, stacks, queues and binary trees, as well as chapters on multi-threading and networking, in addition to its thorough and integrated coverage of graphical user interfaces. When using this text for a one semester CS 1 course, I use roughly half of the content. I would probably not use it for a non-major's CS 0 course, as it could be an overwhelming amount of material for students.

The book is excellent for self-study - many students love having all the extra material available even if we don't cover it in class.

One area where I would have like to have seen more content is in the books coverage of recursion. There is one section in chapter nine dealing with recursion which contains four examples. Recursion is also used for implementing lists and trees, but it would be nice to have a slightly longer treatment as it is a confusing topic for many beginning students.

The text does not include an index. The book itself also does not contain a glossary, but there is one on the companion web site. The text includes quizzes at the end of each chapter, as well as programming exercises.

I did not notice any technical errors or inaccuracies in the book.

The book mostly covers Java 7, with some treatment of Java 8 features, so as of now, the book is perfectly up to date. Future changes to Java likely won't necessitate major changes to the text, and the author has updated the text several times (currently on version 7).

The one area of slight concern is with the Swing library used to build GUI applications. Oracle has replaced Swing with JavaFX, which is the new preferred way of writing GUIs in Java. Still, Swing is widely used and a fine thing to use for introductory courses. Moreover, Swing will be a supported part of Java for a long time as it is still so widely used.

I think the clarity of writing is the best feature of this text. The author uses an easy to read, conversational writing style. The text is also very thorough in its explanations.

The author does a good job using consistent terminology. He explains new terms which are introduced and is very careful about phrasing in general. For instance when talking about objects he has this to say:

"It is certainly not at all true to say that the object is 'stored in the variable std.' The proper terminology is that 'the variable std refers to or points to the object".

Actually speaking about the terminology explicitly like this is really helpful.

The text does use the term "subroutine". While it is internally consistent about this, it is not really consistent with other sources which nearly always refer to them as "methods" in the context of Java. It is not a big point, but students may be confused because they are not called subroutines in other resources they may consult.

The text is as modular as any other introductory programming text book I have seen. It wouldn't be possible to make sense of the example programs in later chapters without a solid mastery of the material in earlier chapters, but that's expected with this type of text. That said, the book does a good job of being as modular as it can. For instance, several of the later sections in a chapter can be skipped over, and, as I describe below, I re-arrange the material slightly to fit my course.

One caveat to this is that many of the examples in later chapters make use of the GUI programming from chapter six. When considering this text, you should be aware that its use of graphics is pretty fundamental and not something you could easily skip over. I see this as a positive as it adds some interest to the example programs which are graphical.

I like the organization of the book quite a lot. It does not use the "objects first" approach. Objects and classes are covered in chapter five, after the basic programming building blocks such as control structures and methods. I did find that some of the later sections within a chapter were things I didn't want to introduce to students at that point. For instance I skip the section on exceptions at the end of chapter three, and the sections on interfaces and nested classes at the end of chapter five.

I do think that the putting off arrays until chapter seven is a mistake, mostly because it is just hard to give good assignments that don't use arrays. When teaching with this book, I cover chapter seven after chapter four.

Overall though, the book does a fine job of transitioning from one topic to the next as it covers not only the particulars of the Java programming language, but the art of programming itself.

I did not find any interface issues at all. The text includes helpful PDF links in the table of contents, and also when the text makes a reference to another section. When discussing the example programs, the author also includes links to the full code on the book's web site, which is helpful. Figures are easy to read and high resolution. One suggestion I would have to improve the interface would be to include syntax highlighting for code listings.

The text is remarkably well edited for its length. I only noticed a handful of spelling or grammatical errors in the book.

I didn't notice any instances of the text being culturally insensitive. The text did not refer to people very often at all. In the few times it mentions the user or programmer, the author uses male and female pronouns equally. For instance at one point the text will mention a guess the number program telling the user "he lost", and later on saying a blackjack program should quit when the user wants to or when "she runs out of money".

I think this book is superior to other introductory programming texts that I have used, even without considering the fact that it is open and free. It is very detailed and provides clear expositions and great examples on everything that can be included in an introductory course (and then some). The few criticisms I have for the book can be easily worked around.

About the Book

Welcome to the Eighth Edition of Introduction to Programming Using Java, a free, on-line textbook on introductory programming, which uses Java as the language of instruction. This book is directed mainly towards beginning programmers, although it might also be useful for experienced programmers who want to learn something about Java. It is not meant to provide complete coverage of the Java language.

The eighth edition requires Java 8 or later, and it uses JavaFX for GUI programming. Version 8.1 is a small update of Version 8.0. This version briefly covers some of the new features in Java 11 and makes it clearer how to use this book with Java 11 and later.

Java programs – 500+ simple & basic programs with outputs.

in Java Programs , Java Tutorials April 20, 2024 Comments Off on Java Programs – 500+ Simple & Basic Programs With Outputs

Java programs: Basic Java programs with examples & outputs. Here we covered over the list of 500+ Java simple programs for beginners to advance, practice & understood how java programming works. You can take a pdf of each program along with source codes & outputs.

In case if you are looking out for C Programs , you can check out that link.

We covered major Simple to basic Java Programs along with sample solutions for each method. If you need any custom program you can contact us.

All of our Sample Java programs with outputs in pdf format are written by expert authors who had high command on Java programming. Even our Java Tutorials are with rich in-depth content so that newcomers can easily understand.

1. EXECUTION OF A JAVA PROGRAM   

Static loading :  A block of code would be loaded into the RAM before it executed ( i.e after being loaded into the RAM it may or may not get executed )

Dynamic loading:   A block of code would be loaded into the RAM only when it is required to be executed.

Note:   Static loading took place in the execution of structured programming languages. EX:  c- language

Java  follows the Dynamic loading

–     JVM would not convert all the statements of the class file into its executable code at a time.

–     Once the control comes out from the method, then it is deleted from the RAM and another method of exe type will be loaded as required.

–     Once the control comes out from the main ( ), the main ( ) method would also be deleted from the RAM. This is why we are not able to view the exe contents of a class file.

Simple Hello Word Program

Out of 500+ Simple & Basic Java Programs: Hello world is a first-ever program which we published on our site. Of course, Every Java programmer or C programmer will start with a “Hello World Program”. Followed by the rest of the programs in different Categories.

Conversion Programs:

Star & Number Pattern Programs

Functions of JVM:

• It converts the required part if the bytecode into its equivalent executable code.
• It loads the executable code into the RAM.
• Executes this code through the local operating system.
• Deletes the executable code from the RAM.

We know that JVM converts the class file into its equivalent executable code. Now if a JVM is in windows environment executable code that is understood by windows environment only.

Similarly, same in the case with UNIX or other or thus JVM ID platform dependent.

Java, With the help of this course, students can now get a confidant to write a basic program to in-depth algorithms in C Programming or Java Programming to understand the basics one must visit the list 500 Java programs to get an idea.

Users can now download the top 100 Basic Java programming examples in a pdf format to practice.

But the platform dependency of the JVM is not considered while saying Java is platform independent because JVM is supplied free of cost through the internet by the sun microsystems.

Platform independence :

Compiled code of a program should be executed in any operating system, irrespective of the as in OS in which that code had been generated. This concept is known as platform independence.

• The birth of oops concept took place with encapsulation.
• Any program contains two parts.
• Date part and Logic part
• Out of data and logic the highest priority we have given to data.
• But in a structured programming language, the data insecurity is high.
• Thus in a process, if securing data in structured prog. lang. the concept of encapsulation came into existence.

Note: In structured programming lang programs, the global variable play a vital role.

But because of these global variables, there is data insecurity in the structured programming lang programs. i.e functions that are not related to some variables will have access to those variables and thus data may get corrupted. In this way data is unsecured.

“This is what people say in general about data insecurity. But this is not the actual reason. The actual concept is as follows”.

Let us assume that, we have a ‘C’ program with a hundred functions. Assume that it is a project. Now if any upgradation is required, then the client i.e the user of this program (s/w) comes to its company and asks the programmers to update it according to his requirement.

Now we should note that it is not guaranteed that the programmers who developed this program will still be working with that company. Hence this project falls into the hands of new programmers.

Automatically it takes a lot of time to study. The project itself before upgrading it. It may not be surprising that the time required for writing the code to upgrade the project may be very less when compared to the time required for studying the project.

Thus maintenance becomes a problem.

If the new programmer adds a new function to the existing code in the way of upgrading it, there is no guarantee that it will not affect the existing functions in the code. This is because of global variables. In this way, data insecurity is created.

• To overcome this problem, programmers developed the concept of encapsulation .
• For example, let us have a struc.prog.lang. program with ten global variables and twenty functions.
• It is sure that all the twenty functions will not use all the global variables .

Three of the global variables may be used only by two functions. But in a structured prog. Lang like ‘C’ it is not possible to restrict the access of global variables by some limited no of functions.

Every function will have access to all the global variables.

To avoid this problem, programmers have designed a way such that the variables and the functions which are associated with or operate on those variables are enclosed in a block and that bock is called a class and that class and that class is given a name, Just as a function is given a name.

Now the variables inside the block cannot be called as the local variable because they cannot be called as global variables because they are confined to a block and not global.

Hence these variables are known as instance variables

_______________________________________________________________

Example 2 :

Therefore a class is nothing but grouping data along with its functionalities.

Note 1:  E ncapsulation it’s the concept of binding data along with its corresponding functionalities.

Encapsulations came into existence in order to provide security for the data present inside the program.

Note 2: Any object oriental programming language file looks like a group of classes. Everything is encapsulated. Nothing is outside the class.

• Encapsulation is the backbone of oop languages.
• JAVA supports all the oop concepts ( i.e. encapsulation, polymorphism, inheritance) and hence it is known as an object-oriented programming language.
• C++ breaks the concept of encapsulation because the main ( ) method in a  C++ program is declared outside a class. Hence it is not a pure oop language, in fact, it is a poor oop language.
