Java Program: Square and Cube of a Number (Using *)

Java

import java.util.Scanner;
 
public class SquareCubeCalculator {
    public static void main(String[] args) {
 
        Scanner sc = new Scanner(System.in);
 
        System.out.print("Enter a number: ");
        int num = sc.nextInt();
 
        int square = num * num;
        int cube = num * num * num;
 
        System.out.println("\nSquare of " + num + " = " + square);
        System.out.println("Cube of " + num + " = " + cube);
 
        sc.close();
    }
}

Output

 
INPUT :
Enter a number: 4

OUTPUT :
Square of 4 = 16
Cube of 4 = 64

Explanation

✔ 1. Square Calculation

The square of a number is:

number × number

Code:

int square = num * num;

✔ 2. Cube Calculation

The cube of a number is:

number × number × number

Code:

int cube = num * num * num;

✔ 3. Why Use * Operator?

Avoids using built-in methods like Math.pow()
Faster and simpler for basic calculations
Good for understanding arithmetic fundamentals
