Java Program that reads an integer between 0 and 1000 and adds all the digits in the integer.

import java.util.Scanner;
public class Exercise8 {

    public static void main(String[] args)
    {
        Scanner in = new Scanner(System.in);
        System.out.print("Input the side length value: ");
        double val = in.nextDouble();

        System.out.printf("Square: %12.2f\n", val * val);
        System.out.printf("Cube: %14.2f\n", val * val * val);
        System.out.printf("Fourth power: %6.2f\n", Math.pow(val, 4));
    }
