Introduction

Java is one of the most popular programming languages used for developing various types of applications. It is widely used in the industry for its platform independence and object-oriented programming capabilities. To learn Java effectively, it is essential to have a good resource that provides a comprehensive understanding of the language. One such resource is the book "Thinking in Java" by Bruce Eckel. In this article, we will discuss how to download the electronic version of this book and provide some code examples to illustrate the concepts covered in the book.

Downloading "Thinking in Java" Electronic Version

To download the electronic version of "Thinking in Java", you can follow the steps below:

1. Open a web browser and go to the website
2. Scroll down until you find the section "Electronic Distribution".
3. Click on the link "Download Source Code" to download the source code examples used in the book.
4. Click on the link "Download Entire Book in PDF" to download the complete book in PDF format.

Code Examples

Now that you have downloaded the electronic version of "Thinking in Java", let's explore some code examples to understand the concepts covered in the book.

Hello World Example

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

In this example, we create a simple Java program that prints "Hello, World!" to the console. The public static void main(String[] args) is the entry point of the program, and System.out.println() is used to print the message.

Object-Oriented Programming Example

public class Circle {
    private double radius;

    public Circle(double radius) {
        this.radius = radius;
    }

    public double getArea() {
        return Math.PI * radius * radius;
    }
}

public class Main {
    public static void main(String[] args) {
        Circle circle = new Circle(5.0);
        double area = circle.getArea();
        System.out.println("Area of the circle: " + area);
    }
}

In this example, we define a class Circle which represents a circle object. It has a private field radius and a constructor to initialize it. The getArea() method calculates the area of the circle using the formula Math.PI * radius * radius. In the Main class, we create an instance of the Circle class and calculate its area.
