Assalamu’alaikum wr wb,
Dalam penjelasan projek
kali ini sama dengan yang saya jelaskan dalam tugas kemarin. Yaitu program
penjualan menggunakan JAVA GUI,untuk menjalankannya program ini user hanya
memilih berupa kode barang,kode yang dipilih akan dikalikan dengan jumlah yang
akan dibeli.User juga bisa memilih merk barang dan ukuran sepatu yang akan
dibeli dengan menggunakan combo box.Jika sudah membeli user bisa langsung
keluar dengan memilih button “Keluar” menggunakan Joptionpane.
