- Menampilkan jendela login dengan menu, untuk menampilkan jendela lain yang berisi tampilan tabel
- Connection hanya diinisiasi sekali didalam jendela login. Selanjutnya connection di digunakan didalam jendela lain
Berikut ini adalah kode program untuk jendela login yang bernama JavaFXTampilan.java :
