Tugas 3 PBO A

Hey guys! This time I have been working on making my own Ticket Machine using BlueJ.
I am using 2 classes, which is Main and TicketMachine.

1. TicketMachine

    /*  
     * This class contains the declaration of the Ticket Machine we are going to use..  
     *

     */  
    import java.util.Scanner;  
      
    public class TicketMachine{   
      Scanner scan = new Scanner(System.in);  
      // The price of a ticket from this machine.   
      private int price;   
      // The amount of money entered by a customer so far.   
      private int balance;  
      // The amount of tickets about to be printed.  
      private int ticket;  
      // The total amount of money collected by this machine.   
      private int total;  
      /*   
       * Create a machine that issues tickets of the given price.   
       * Note that the price must be greater than zero, and there   
       * are no checks to ensure this.   
       */   
      public TicketMachine(int ticketCost){   
        price = ticketCost;   
        balance = 0;   
        total = 0;  
        ticket = 0;  
      }   
      /*   
       * Return the price of a ticket.   
       */   
      public int getPrice() {   
        return price;   
      }   
      /*   
       * Return the amount of money already inserted for the   
       * next ticket.   
       */   
      public int getBalance(){   
        return balance;   
      }   
      /*   
       * Receive an amount of money in cents from a customer.   
       */   
      public int insertMoney(int amount){  
        balance = balance + amount;  
        return balance;  
      }   
      /*   
       * Print a ticket.   
       * Update the total collected and   
       * reduce the balance to zero.   
       */   
      public int printTicket(int ticket){   
        // Simulate the printing of a ticket.  
        for(int i = 0; i < ticket; i++){  
          System.out.println("======================");   
          System.out.println("The BlueJ Line Ticket");    
          System.out.println("Price: Rp " + price + ",00");  
          System.out.println("======================\n");  
        }  
        // Update the total collected with the balance.   
        total = total + balance;   
        // Clear the balance and the ticket.   
        balance = balance - (ticket * price);  
        return balance;  
      }   
    }  
   

2. Main

      
    /*

      public static void main(String args[]){   
        Scanner scan = new Scanner(System.in);   
        int cost, menu, balance = 0;  
        int amount = 0;  
        boolean printed = false;  
        System.out.print("Input the ticket price: Rp ");   
        cost = scan.nextInt();  
        TicketMachine ticket = new TicketMachine(cost);  
        System.out.println();  
        while(true){   
          System.out.println("1. Get Price");

            cost=ticket.getPrice();   
            System.out.println("Price: Rp " + cost + ",00\n");   
            break;   
            case 2:   
            balance = ticket.getBalance();  
            System.out.println("Balance: Rp " + balance + ",00\n");  
            break;   
            case 3:   
            int money = scan.nextInt();   
            balance = ticket.insertMoney(money);   
            break;   
            case 4:  
            System.out.print("Total tickets: ");  
            amount = scan.nextInt();  
            if(balance >= (amount * cost)){  
              balance = ticket.printTicket(amount);  
              printed = true;  
            }  
            else{  
              System.out.println("Balance insufficient. Please insert enough balance to proceed.\n");  
            }  
            break;  
            case 5: break;  
          }  
          if(menu == 5) break;  
        }  
        System.out.println("\nThank you for using BlueJ Line!\n");  
        System.out.println("Your balance: Rp " + balance + ",00");  
      }   
   }
   

Using those codes above, it will look like this:

Thank you and see you next time!
