Compute square & cube of a number - Java Program

Java

import java.util.Scanner;
 
public class SquareCube {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
 
        // Taking input from user
        System.out.print("Enter a number: ");
        int num = sc.nextInt();
 
        // Calculating square and cube
        int square = num * num;
        int cube = num * num * num;
 
        // Displaying the result
        System.out.println("Square of " + num + " = " + square);
        System.out.println("Cube of " + num + " = " + cube);
 
        sc.close();
    }
}

Output

 
OUTPUT 1:
Enter a number: 5
Square of 5 = 25
Cube of 5 = 125

OUTPUT 2:
Enter a number: -3
Square of -3 = 9
Cube of -3 = -27

Explanation

✅ Step 1: Take input

The program reads an integer from the user using Scanner:

int num = sc.nextInt();

✅ Step 2: Compute square

Square = number × number

int square = num * num;

✅ Step 3: Compute cube

Cube = number × number × number

int cube = num * num * num;

✅ Step 4: Display the results

Using:

System.out.println(...)

This provides clear output for the user.
