Program Ticket Machine

          Pagi, bagaimana kabarnya semua? Semoga sehat selalu ya :)

          Pada kesempatan kali ini saya akan mempublish mengenai tugas kuliah saya yang implementasinya sangat dibutuhkan di kehidupan sehari-hari.

          Ya, program pada tugas kali ini yaitu "Ticket Machine". Seperti namanya, Ticket Machine merupakan mesin yang berfungsi untuk melayani penjualan tiket. Baik itu tiket kereta api, pesawat, atau yang lainnya. Langsung saja, berikut kodingannya menggunakan Java di BlueJ.

   System.out.println();

 }  
 //Main  
 import java.util.Scanner;  
 public class IntMain  
 {  
 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();  
  TicketMachine ticket=new TicketMachine(cost);System.out.println(“1. Get Price”);  
  System.out.println(“2. Get Balance”);  
  System.out.println(“3. Insert Money”);  
  System.out.println(“4. Print Ticket”);  
  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;  
  }  
  }  
 }  

                                                                                                                                                                   

            Dan setelah di compile program tersebut akan berjalan seperti pada gambar berikut :
