Create a program that allows a user to input customer records (ID number, first name, last name, and balance owed) and save each record to a file. When you run the main program, be sure to enter multiple records.

Once you create the file, open it and display the results to the user

Save the file as CustomerList.java

Expert Solution

import java.io.File;
import java.io.PrintWriter;
import java.util.Scanner;

public class CustomerList {
   public static void main(String[] args) throws Exception {
       Scanner sc = new Scanner(System.in);
       PrintWriter pw = new PrintWriter(new File("output.txt"));
       int id;
       String fname, lname;
       double balance;
       String ch = "y";
       //reading the data
       while (ch.equalsIgnoreCase("y")) {
           System.out.println("Enter Id: ");
           id = sc.nextInt();
           //reading the data from user
           System.out.println("Enter first Name and Last name");
           fname = sc.nextLine();
           fname = sc.nextLine();
           lname = sc.nextLine();
           System.out.println("Enter balance: ");
           balance = sc.nextDouble();
           //printing the data to the file
           pw.println(id + "\t" + fname + " " + lname + "\t" + balance);
           System.out.println("Press y/Y to continue, any other key to exit: ");
           ch = sc.nextLine();
           ch = sc.nextLine();
       }
       pw.close();
       //opening the file and reading and printing
       sc = new Scanner(new File("output.txt"));
       while (sc.hasNext()) {
           System.out.println(sc.nextLine());
       }
