How Java Was Created?

The history of Java started in 1991 when a team at Sun Microsystems began a project called Green Project. The main goal was to create a programming language for electronic devices.

James Gosling created Java, which was first named Oak. Later, the name was changed to Java in 1995.

First Release of Java

Java was officially released by Sun Microsystems in 1995. It became popular because programs written in Java could run on different platforms using the Java Virtual Machine (JVM).

Example


public class HelloJava{ 
    public static void main(String[] args) {
        System.out.println("Hello Java");
    }
    }

Output

Hello Java
