in this tutorial, we will learn how to calculate the square of a number in a Java



Example:

package javaapplication;

import java.util.Scanner;

/**
 * @author Rathorji
 */
public class JavaApplication {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);
        int num;

        System.out.print("Enter an integer number: ");
        num = sc.nextInt();

        System.out.println("Square of " + num + " is: " + Math.pow(num, 2));

    }

}


output:

run:
Enter an integer number: 144
Square of 144 is: 20736.0
