Java Day 2: Operators

Given the meal price (base cost of a meal), tip percent (the percentage of the meal price being added as tip), and tax percent (the percentage of the meal price being added as tax) for a meal, find and print the meal's total cost.

Note: Be sure to use precise values for your calculations, or you may end up with an incorrectly rounded result!



  1. import java.util.Scanner;

  2. 

  3. public class Solution {

  4.     public static void main(String[] args) {

  5.         Scanner scan = new Scanner(System.in);

  6.         double mealCost = scan.nextDouble(); // original meal price

  7.         int tipPercent = scan.nextInt(); // tip percentage

  8.         int taxPercent = scan.nextInt(); // tax percentage

  9.         scan.close();

  10. 

  11.         // Write your calculation code here.

  12.         double tip = mealCost * tipPercent / 100;

  13.         double tax = mealCost * taxPercent / 100;

  14. 

  15.         // cast the result of the rounding operation to an int and save it as totalCost

  16.         int totalCost = (int) Math.round(mealCost + tip + tax);

  17. 

  18.         // Print your result

  19.         System.out.println(totalCost);

  20.     }
