Question

Write a Java application that determines whether any of several department store customers has exceeded the credit limit on a charge account. For each customer, the following facts are inputted:

Account number
Balance at beginning of month
Total amount of all items charged by the customer this month
Total amount of all credits applied to the customer’s account this month
Allowed credit limit

Use the value of -1 as a sentinel value to quit the program. The program should input all these facts, calculate the new balance ( beginning balance + charges – credits), display the new balance and determine whether the new balance exceeds the customer’s credit limit. For those customers whose credit limit is exceeded, the program should display the message “Credit limit exceeded”.

Use the sentinel control algorithm shown in class and the textbook if you want a passing grade on this lab assignment.

Answer 1

Please find the code below:

CreditLimitCheck.java

package classes3;

import java.util.Scanner;

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

       int accountNumber;
       double balance;
       double charges;
       double credit;
       double creditLimit;
       double newBalance;

       while(true){
           System.out.print("Enter account number : ");
           accountNumber = sc.nextInt();
           if(accountNumber==-1){
               break;
           }

           System.out.print("Enter Balance at beginning of month : ");
           balance = sc.nextDouble();
           if(balance==-1){
               break;
           }

           System.out.print("Enter Total amount of all items charged by the customer this month : ");
           charges = sc.nextDouble();
           if(charges==-1){
               break;
           }

           System.out.print("Enter Total amount of all credits applied to the customer’s account this month : ");
           credit = sc.nextDouble();
           if(credit==-1){
               break;
           }

           System.out.print("Enter Allowed credit limit : ");
           creditLimit = sc.nextDouble();
           if(creditLimit==-1){
               break;
           }

           newBalance = balance+charges-credit;

           if(newBalance>creditLimit){
               System.out.println("Credit Limit Exceeded");
           }
           System.out.println("**********");

       }

   }
}

output:
