Tugas Integra PBO-B

Pada kesempatan kali ini saya akan mencoba membuat sistem integra. Disini saya nantinya akan membuat 8 class dengan menggunakan metode inheritance. Berikut adalah penggambaran classnya dengan menggunakan Blue J.

Berikut adalah source code tiap classnya.

1. Database
   

    /**  
     * Write a description of class Database here.  
     *  
     * @author (your name)  
     * @version (a version number or a date)  
     */  
    import java.util.ArrayList;  
    public class Database  
    {  
      private ArrayList<ID>id;  
      public Database()  
      {  
        id=new ArrayList<ID>();  
      }  
      public void addID(ID theID)  
      {  
        id.add(theID);  
      }  
      public void list()  
      {  
        for (ID id:id){  
          id.print();  
          System.out.println();  
        }  
      }  
    }

        nama=theNama;  
      }  
      public void print()  
      {
