Write a Java program to print an integer

In this tutorial, we will discuss a simple concept of Write a Java program to print an integer

In this post, we are going to learn about how to print an integer number entered by the user in Java programming language

The value is stored in a variable num using Scanner class(System.in) and it is displayed on the screen using System.out.print() statements.

Program 1

import java.util.Scanner;
class PrintInt{
public static void main (String args[]){

Scanner scan=new Scanner(System.in);
//create a scanner object for receives input
//from the user - input from keyboard
System.out.print("Enter the number: ");

int num=scan.nextInt();
//reads the integer value from the user
//input from keyword

System.out.print("You entered : "+num);
}
}

When the above code is executed, it produces the following results

Enter the number:999
you entered : 999

In the Java program, the user can enter a value using scanner class and that value stored in a variable named as num. then prints that value using display statements in Java language

In this program, System.out.print() provides a piece of information to the user for entering an integer value

System.out.print("Enter the number: ");

Then, it reads an integer value from the user and stores in variable num

int num=scan.nextInt();

Finally, the value stored in the variable num is displayed on the screen by using System.out.print() method

System.out.print("You entered : "+num);
