Hello world in Java

Java is an object oriented programming language. Every Java program start with a class definition. The file name of Java should be same as the class name. The following program prints “Hello world”.

package com.company;

public class Main {

    public static void main(String[] args) {

        System.out.println("Hello World");

    }
}

Output:

Hello World

The public static void main is the main method and should be present in all Java programs. Program execution starts from the main method. The statement System.out.println() has a println() method which prints “Hello World” on the screen.
