How to calculate percentage in Java ?.

Program to demonstrate how to calculate percentage in Java

package com.hubberspot.code;

import java.util.Scanner;


public class PercentageCalculator {

 public static void main(String[] args) {

  // Create two variables x and y initially assigned
  // to a value 0.

  double x = 0;
  double y = 0;

  // Create a Scanner object which takes System.in object
  // this makes us read values from the console

  Scanner scanner = new Scanner(System.in);

  // In order to Calculate (x % of y) ?...
  // We will prompt user to enter values 
  // of x and y 

  // Prompting user to enter value of x 
  System.out.println("Enter the value of x : ");

  // Scanner objects nextDouble reads output from the console
  // entered by user and stores into the double variable
  x = scanner.nextDouble();  

  // Prompting user to enter value of y  
  System.out.println("Enter the value of y : ");

  // Scanner objects nextDouble reads output from the console
  // entered by user and stores into the double variable
  y = scanner.nextDouble();

  System.out.println();


  System.out.println("Calculating percentage : (x % of y) : ");

  // In order to calculate x percent of y  
  // we use the following formula and store the result
  // in a variable called as result
  double result = x * y / 100;

  // printing the result on the console
  System.out.println(x + " % of " + y + " is " + result); 

  System.out.println();

 }
