Cerita Kita: Tugas 3 PBO-A Membuat Ticket Machine

Setelah membuat gambar grafik pemandangan dengan bahasa Java, sekarang saatnya untuk membuat simulai Ticket Machine.
Disini saya membuat dua class yaitu :

1. IntMain
2. TicketMachine

Berikut adalah sourcecodenya:

 /**  
  * IntMain sebagai fungsi utama  
  *  
  * @author (Lutfiyanti)  
  * @version (17-09-2018)  
  */  
 import java.util.Scanner;  
 public class IntMain  
 {    
   public static boolean isPrinted;   
   public static void main(String args[])  
   {  
     Scanner scan = new Scanner(System.in);  
     int cost, menu;  
     System.out.println("Masukkan harga tiket \n");  
     cost = scan.nextInt();  
     TicketMachines ticket=new TicketMachines(cost);   
     System.out.println("1. Cek harga");  
     System.out.println("2. Cek Saldo");  
     System.out.println("3. Masukkan uang");  
     System.out.println("4. Cetak Tiket");  
     System.out.println("5. Keluar Menu");  
     while (isPrinted!=true){  
     menu = scan.nextInt();  
     switch(menu)  
     {  
       case 1:  
       cost = ticket.getPrice();  
       System.out.println(cost);  
       break;  
       case 2:  
       ticket.getBalance();  
       break;  
       case 3:  
       int money = scan.nextInt();  
       ticket.insertMoney(money);  
       break;  
       case 4 :  
       ticket.printTicket();  
       break;   
       case 5 :  
       isPrinted=true;  
       break;  
     }  
   }  
 }  
 }

Berikut adalah outputnya dengan dua case yaitu uang yang dimasukkan kurang dan berlebih :
