Baik mungkin itu saja pembukaan yang ingin saya ucapkan di sini.
Oke kita lanjutkan saja tentang artikel "Contoh Program Penjualan Menggunakan Java NetBeans" Dimana jaman semakin canggih dari tahun ke tahun apa apa semua memakai sistem komputer mulai dari program sampai ke database pun memakai komputer, Seperti yang kita ketahui bahwa sebuah bisnis di era digital kini semakin naik naik nya apa apa mau serba instan kayak mie instan saja heheheh... Dalam proses penjualan perlu adanya bukti transaksi yang digunakan untuk merekam semua kegiatan penjualan. Setiap proses transaksi dibutuhkan program untuk mencatat setiap transaksi penjualan sehingga proses lebih cepat. Terinspirasi dari hal tersebut, Saya mencoba membuat program transaksi penjualan menggunakan Java NetBeans. Program ini cukup sederhana dan semoga dapat membantu dalam proses penyimpanan data transaksi penjualan.
Buat
project baru
Jalankan software Java NetBeans dan
membuat sebuah project baru dengan memilih File
> New project > buat nama project Penjualan.
Selanjutnya Anda dapat membuat class
dengan cara Klik kanan pada package > New > Java class dan buat 3 class
dengan nama, seperti: ModelBarang, ModelPenjualan dan Penjualan.
Buat script pada class ModelBarang seperti berikut ini.
