Java Program to Print Hello World

Prerequisites

Before starting with this tutorial, we assume that you are the best aware of the following Java programming topics:

Operators in Java Programming.
Basic Input and Output function in Java Programming.
Basic Java programming.

Printing a message:-

Message passing is a very important feature for object-oriented programming. Here in this program, we will print the message to the user for hello world.

Algorithm to Print Hello World in the output:-

1. Declaring the variables for the program.

2. Defining the input value for the variable in string format.

3. Printing the data taken in input from the user in string format.

4. End program.

1. Declaring the variables for the program.

2. Defining the input value for the variable in string format.

3. Printing the data taken in input from the user in string format.

4. End program.

Program to Print Hello World

The string is a collection of characters in Java programming. The string is used for sending messages on the screen. In Java programming, we can take the input from the user in string format. In this program, we will define input in string format. The second will print the string “Hello World” with the help of a small program. The String is the most useful datatype in any programming language. The message passing in any program is very important. It is also a part of the object-oriented programming (OOP’s) concept.

Program to Print Hello World:-

// Program to print the hello world program in java
import java.util.*;//Importing the package for the program.

public class HW {//Creating the class for the program in public type
    //Body of Main function of the program
    public static void main(String[] args) {
        
        //Declaring the required variable for the program.
        //String type variable to hold message.
        String s ="Hello, World!";
        //Prinint the hello world to the user
        //Using the System.out.println();
        System.out.println(s); 
    }
}

// Program to print the hello world program in java

import java.util.*;//Importing the package for the program.

public class HW {//Creating the class for the program in public type

//Body of Main function of the program

public static void main(String[] args) {

//Declaring the required variable for the program.

//String type variable to hold message.

String s ="Hello, World!";

//Prinint the hello world to the user

//Using the System.out.println();

System.out.println(s);

}

Output:-

In the above program, we have first initialized the required variable.

s = it will hold the input string value from the user.

Importing the util package for the program.

Printing the data in the output in the string format.
