• Java is a popular programming language that is used to develop mobile apps, web apps, desktop apps, games and much more³. It is an object-oriented, class-based, concurrent, secured and general-purpose language⁶. It was developed by James Gosling at Sun Microsystems in 1991⁵.

• Object-oriented programming
• Inheritance and polymorphism
• Interfaces and abstract classes
• Generics and collections
• Exceptions and assertions
• Input/output streams
• Threads and concurrency

To run this project, you need to have Java Development Kit (JDK) installed on your machine. You can download it from here.

You also need to have an Integrated Development Environment (IDE) that supports Java, such as Eclipse, IntelliJ IDEA, or NetBeans. You can download them from their respective websites.

There are many reasons why Java is so popular among developers and programmers. Some of them are:

• Java is platform-independent, which means it can run on any machine that has a Java Runtime Environment (JRE) installed¹².
• Java is object-oriented, which means it simplifies complex problems by using classes and objects that encapsulate data and behavior²³.
• Java has a rich set of APIs that provide thousands of classes and methods for various tasks such as networking, database connectivity, user interface, etc².
• Java has a strong and active community that supports and helps each other through forums, blogs, tutorials, etc⁴⁵.
• Java is secure and robust, which means it has built-in features to prevent malicious attacks and handle errors gracefully²³.
• Java is versatile and powerful, which means it can be used for various types of applications such as web apps, mobile apps, desktop apps, games, big data, IoT, etc³.

There are many books that can help you learn Java, depending on your level of expertise and your learning goals. Some of the best Java books that are recommended by many sources are:

• Effective Java by Joshua Bloch²³: This book offers 78 best practices to follow for writing better and more effective Java code. It covers topics such as concurrency, generics, methods, enums, annotations, etc. It is suitable for intermediate to advanced Java programmers who want to improve their skills and knowledge.
• Head First Java by Kathy Sierra and Bert Bates²⁴: This book is a brain-friendly guide that uses a visual and engaging approach to teach Java concepts. It covers topics such as object-oriented programming, inheritance, polymorphism, interfaces, exceptions, threads, etc. It is suitable for beginners who want to learn Java in a fun and interactive way.
• Learning Java by Marc Loy, Patrick Niemeyer and Daniel Leuck⁵: This book is an introduction to real-world programming with Java. It covers topics such as data structures, algorithms, lambda expressions, streams, modules, networking, database connectivity, etc. It is suitable for beginners who want to learn how to use Java for practical applications.
• Core Java Volume I — Fundamentals by Cay S. Horstmann¹: This book is a comprehensive guide that covers the core features of Java SE (Standard Edition). It covers topics such as language basics, exception handling, interfaces, lambda expressions, collections framework etc. It is suitable for beginners who want to master the fundamentals of Java SE.

These are some of the best Java books that you can read to learn more about this popular programming language. You can also check out other books that suit your preferences and needs. Happy reading! 😊

4. Write a Java program that creates a user interface to perform integer divisions. The user enters two numbers in the text fields, Num1 and Num2. The division of Num1 and Num 2 is displayed in the Result field when the Divide button is clicked. If Num1 or Num2 were not an integer, the program would throw a Number Format Exception. If Num2 were Zero, the program would throw an Arithmetic Exception. Display the exception in a message dialog box. View Solution
