Question

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

import java.util.*;

public class Main {

public static void main(String[] args)

{

Scanner scan = new Scanner();

double budget=0, num=0, total=0;

System.out.println("Your budget for the month? ");

budget=scan.nextDouble();

System.out.println("enter all expense, and after that type -9999 to quit: ");

while(num != -9999)

{

total+=num;

num=scan.nextDouble();

}

if(total<=budget)

{

System.out.println("under budget by ");

System.out.println(budget-total);

}

else

{

System.out.println("over budget by ");

System.out.println(total-budget);

}

}

}

Step-by-step explanation:

• Take the budget as an input from user and store it to the budget variable.
• Loop until user has entered all his expenses and keep on adding them to the total variable.
• Check If the total is less than or equal to budget or otherwise, and then print the relevant message accordingly.
