Database Akademik (Inheritance)
Tugas Pemrograman Berbasis Objek (PBO)
Membuat Database Akademik (Inheritance)
Kali ini saya akan membuat database akademik menggunakan BlueJ dengan konsep inheritance. Berikut source code dan tampilan akhirnya. Saya membutuhkan 1 superclass (Database), 6 subclass (Mahasiswa, Kelas, Matkul, Dosen, Buku, dan Pegawai), dan 1 class (TestDatabase).
1. Source Code Database
/**
* Write a description of class Database here.
*
* @author Yuki Yanuar Ratna
* @version 15/11/2018 v.1
*/
public class Database
{
private String nama;
private String id;
public Database (String n, String i)
{
nama = n;
id =i;
}
public String toString ()
{
return "Database[nama=" + nama + ",id=" + id + "]";
}
}
2. Source Code Mahasiswa
/**
* Write a description of class Mahasiswa here.
*
* @author Yuki Yanuar Ratna
* @version 15/11/2018 v.1
*/
public class Mahasiswa extends Database
{
private String jurusan;
private String alamat;
private String agama;
public Mahasiswa (String n, String i, String j, String a1, String a2)
{
super (n,i);
jurusan = j;
alamat = a1;
agama = a2;
}
public String toString()
{
return "Mahasiswa[super=" + super.toString() + ",jurusan=" + jurusan + ",alamat=" + alamat + ",agama=" + agama + "]";
}
}
3. Source Code Kelas
/**
* Write a description of class Kelas here.
*
* @author Yuki Yanuar Ratna
* @version 15/11/2018 v.1
*/
public class Kelas extends Database
{
private int totalSiswa;
public Kelas (String n, String i, int t)
{
super (n,i);
totalSiswa = t;
}
public String toString ()
{
return "Kelas[super=" + super.toString() + ",totalSiswa=" + totalSiswa + "]";
}
}
4. Source Code Matkul
/**
* Write a description of class Matkul here.
*
* @author Yuki Yanuar Ratna
* @version 15/11/2018 v.1
*/
public class Matkul extends Database
{
private String semester;
public Matkul (String n, String i, String s)
{
super(n,i);
semester = s;
}
public String toString()
{
return "Matkul[super=" + super.toString() + ",semester=" + semester + "]";
}
}
5. Source Code Dosen
/**
* Write a description of class Dosen here.
*
* @author Yuki Yanuar Ratna
* @version 15/11/2018 v.1
*/
public class Dosen extends Database
{
private String bidang;
private String alamat;
private String agama;
public Dosen (String n, String i, String b, String a1, String a2)
{
super (n,i);
bidang = b;
alamat = a1;
agama = a2;
}
public String toString()
{
return "Dosen[super=" + super.toString() + ",bidang=" + bidang + ",alamat=" + alamat + ",agama=" + agama + "]";
}
}
6. Source Code Buku
/**
* Write a description of class Buku here.
*
* @author Yuki Yanuar Ratna
* @version 15/11/2018 v.1
*/
public class Buku extends Database
{
private String penulis;
private int tahun;
public Buku (String n, String i, String p, int t)
{
super(n,i);
penulis = p;
tahun = t;
}
public String toString()
{
return "Buku[super=" + super.toString() + ",penulis=" + penulis + ",tahun=" + tahun + "]";
}
}
7. Source Code Pegawai
/**
* Write a description of class Pegawai here.
*
* @author Yuki Yanuar Ratna
* @version 15/11/2018 v.1
*/
public class Pegawai extends Database
{
private String alamat;
private String agama;
public Pegawai (String n, String i, String a1, String a2)
{
super(n,i);
alamat = a1;
agama = a2;
}
public String toString()
{
return "Pegawai[super=" + super.toString() + ",alamat=" + alamat +",agama=" + agama + "]";
}
}
8. Source Code TestDatabase
/**
* Write a description of class TestDatabase here.
*
* @author Yuki Yanuar Ratna
* @version 15/11/2018 v.1
*/
public class TestDatabase

System.out.println("===============DATABASE AKADEMIK INFORMARIKA ITS===============");
System.out.println("\n");
System.out.println("########DATABASE MAHASISWA########");
System.out.println(a1);
