5.3.6 Implementasi Kelas HalamanUtama
Berikut merupakan implementasi dari atribut dan method pada kelas HalamanUtama yang dibuat sesuai dengan perancangannya. Kelas ini berkaitan semua fungsi utama sistem karena bertimdak sebagai interface utama ketika pengguna akan melakukan keseluruhan fungsi pada sistem. Pada listing program ini hanya akan ditampilkan
method utama seperti yang ada pada tabel 4.3.6.6.l pada bab perancangan.
