Ini adalah hasil output jika salah membaca no.kartu karena beberapa alasan seperti kartu tidak terdaftar.

Ini adalah tugas rumah saya membuat Auction System atau bisa disebut sistem lelang dengan menggunakan Java.

Berikut Formatted Source code saya:
a) Person

 public class Person   
  {   
   // The name of this person.   
   private final String name;   
   /**   
   * Create a new person with the given name.   
   */   
   public Person(String name)   
   {   
    this.name = name;   
   }   
   /**   
   * @return The Person's name*   
   */   
   public String getName()   
   {   
    return name;   
   }   
  }   

b) Bid

 public class Bid   
  {   
   private final Person bidder;   
   private final long value;   
   /**   
   * Create a bid    
   */   
   public Bid(Person bidder, long value)   
   {   
    this.bidder = bidder;   
    this.value = value;   
   }   
   /**   
   *@return The bidder.   
   */   
   public Person getBidder()   
   {   
    return bidder;   
   }   
   /**   
   * @return The value of the bid.   
   */   
   public long getValue()   
   {   
    return value;   
   }   
  }   

c) Lot

 public class Lot   
  {   
   private final int number;    
   private String description;    
   private Bid highestBid;

Screenshot jalannya dan output program

Pertama klik class person dan klik newperson() untuk membuat nama siapa aja yang akan mengikuti acara lelang. Anggap saja nama orangnya orang1,orang2, dan orang 3

Lalu klik class auction dan klik enterslot() untuk memasukkan nama orang untuk mengikut acara lelang.

lalu klik void makeABid()(untuk memberikan tawaran seharga yang diinput

Jika kita ingin melihat hasil tawaran sementara bisa menggunakan void showLots() 

klik void close() untuk menutup lelangan dan mengeluarkan hasil akhirnya
