Program to calculate Volume and Surface Area of Cube in Java ?

package com.hubberspot.mensuration.example;

import java.util.Scanner;

public class Cube {

  public static void main(String[] args) {
    Scanner input = new Scanner(System.in);

    double edge = 0;

    double volume = 0;
    double surfaceArea = 0;
 
    System.out.print("Enter the length of edge of Cube : "); 
    edge = input.nextDouble();

    volume = (edge * edge * edge);
    surfaceArea = 6 * (edge * edge);

    System.out.println("");
    System.out.println("The Volume of Cube is : " + volume);
    System.out.println("The Surface Area of Cube is : " + surfaceArea);
  }

}
