Program Penjualan Air Mineral Menggunakan Java NetBeans
Descripsi: Setiap
orang pasti membutuhkan air minum untuk dapat bertahan hidup. Bila
tidak mengkonsumsi air yang cukup dapat menyebabkan Kita mudah terserang
penyakit. Untuk itu, konsumsi air putih minimal 8 gelas atau 2 liter
perhari. Setiap hari permintaan air minum tidak pernah berhenti, bahkan
di daerah tertentu sering terjadi krisis stok air. Hal ini menandakan
bahwa air minum sangat penting karena setiap orang membutuhkan air
minum. Hal ini yang menyebabkan banyak produsen air minum memproduksi
air kemasan dengan berbagai ukuran mulai dari 240 ml hingga 19 Liter.
Air kemasan atau air mineral dapat Kita temukan pada super market,
minimarket hingga warung. Bila membuka bisnis penjualan air mineral
tentu keuntungan akan besar karena banyak permintaan air mineral.
Berbicara mengenai penjualan air mineral, Kami mencoba membuat sebuah
program sederhana untuk penjualan air mineral menggunakan Java NetBeans.
Berikut ini penjelasan cara pembuatan program tersebut:
2. Komponen
- Merk Air Mineral
- ukuran
- Harga satuan
- Jumlah Pembelian
