INTRODUCTION TO JAVA

WHAT IS JAVA?

Ufff... Are you bored with Theory? Let's try something practical how to write a Java program

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

The Structure of the Java program is simple, everything is written in the class, and the above example shows the same main method and statements written in the class HelloWorld.

Being clear is fine, we will learn everything in the flow if confused.

Note: Java is case-sensitive. HelloWorld and helloworld have different meanings, and the Class name and Java file name should be the same.
