Question

16. Budget Analysis Write a program that asks the user to enter the amount that he or she has budgeted for a month. A loop should then prompt the user to enter each of his or her expenses for the month, and keep a running total. When the loop finishes, the program should display the amount that the user is over or under budget.

Answer 1

Answer:

import java.util.Scanner;

public class num8 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter month's budget");

       double monthBudget = in.nextDouble();

       double totalExpenses = 0.0;

       double n;

       do{

           System.out.println("Enter expenses Enter zero to stop");

           n = in.nextDouble();

           totalExpenses += n;

       }while(n>0);

       System.out.println("Total expenses is "+totalExpenses);

System.out.println("The amount over your budget is "+ Math.abs(monthBudget-totalExpenses));

   }

}

Explanation:

• Using Java programming language
• Prompt user for month's budget
• Use Scanner class to receive and store the amount entered in a variable
• Use a do while loop to continuously request user to enter amount of expenses
• Use a variable totalExpenses to add up all the expenses inside the do while loop
• Terminate the loop when user enters 0 as amount.
• Subtract totalExpenses from monthBudget and display the difference as the amount over the budget
