Java Program to Print an Integer Entered by the User

In this post, we will learn how to print an integer entered by the user using Java Programming language.

This program asks the user to enter a number, then it displays the entered number using the System.out.print statement.

So, without further ado, let’s begin this tutorial.

Java Program to Print an Integer Entered by the User

// Java Program to Print an Integer Entered by the User
import java.util.Scanner;
public class NumberPrint{
    public static void main(String[] args){

        // Asking for input
        Scanner reader = new Scanner (System.in);
        System.out.println("Enter an integer: ");
        int num = reader.nextInt();

        // Displaying output
        System.out.println("You entered: " + num);
    }
}

Output

Enter an integer: 
15
You entered: 15

How Does This Program Work ?

        // Asking for input
        Scanner reader = new Scanner (System.in);

In this program, we have created a Scanner reader class to take inputs.

        System.out.println("Enter an integer: ");

Then, the user is displayed a message to enter an integer.

 int num = reader.nextInt();

Now, we used reader.nextInt() to read all the entered integers. The entered integer gets stored in the num named variable.

        // Displaying output
        System.out.println("You entered: " + num);

Finally, the entered number is displayed on the screen using the System.out.println() function.

Conclusion
