Java Data Type Exercises: Reads a number and display the square, cube, and fourth power

Java Data Type: Exercise-8 with Solution

Write a Java program that reads a number and display the square, cube, and fourth power.

Test Data
Input the side length value: 15

Sample Solution:

Java Code:

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));
    }
}

Sample Output:

Input the side length value: 15                                                                               
Square: .2f                                                                                                   
Cube: .2f                                                                                                     
Fourth power: 50625.00

Previous: Write a Java program to display the speed, in meters per second, kilometers per hour and miles per hour.
Next: Write a Java program that accepts two integers and then prints the sum, the difference, the product, the average, the distance (the difference between integer), the maximum (the larger of the two integers), the minimum (smaller of the two integers).
