TOKO ELEKTRONIK SITANGGANG

Nama saya Herlinda Mita M. Sitanggang, saya adalah mahasiswa dari STMIK Eresha. Disini saya membuat program sederhana dengan java swing atau dengan kata lain sudah GUI (Graphic User Interface). Saya membuat program kasir yang tergolong sederhana.

Saya akan menjelaskan,

Saya menggunakan dua (2) Variabel Integer, String . Lalu saya menggunakan beberapa Method yaitu:

JUMLAH: untuk menampilkan jumlah barang item barang yang di beli.

RUPIAH: Jumlah harga barang per item

JUMLAH BELANJA: untuk menampilkan Jumlah barang yang di beli

DISK 20%: untuk menghitung total bayar diskon 20% (Jika belanja Rp.3.000.000)

TOTAL BAYAR: untuk menampilkan TOTAL BAYAR sebelum diskon

CASH: untuk pembayaran CASH

CARD: untuk pembayaran pake CARD (Jika pembayaran pake CARD + Diskon 10%)

VOUCHER: Untuk pembayaran pake VOUCHER (Jika pembayaran pake Voucher mendapat potongan senilai nominal voucher tersebut.)

Ini adalah informasi untuk teks Variabelnya:

Nama Text Variabel

JLabel Judul jLabel1

Jlabel Kasir jLabel2

jLabel Nik jLabel3

jLabel TV jLabel4

jLabel DVD jLabel5

jLabel SOUND SYSTEM jLabel6

jLabel RADIO TAPE jLabel7

jLabel MICROFON jLabel8

jLabel ANTENA jLabel10

jlabel Nama Barang jLabel11

jLabel jumlah jLabel12

jLabel Rupiah jLabel13

jLabel Pembayaran jLabel15

jLabel Jumlah Belanja jLabel16

jRadio Button Disk 20% jRadio Button1

Lebih detailnya akan saya tampilkn SOURCH kodenya,

tekan Shift + F6

tampilannya seperti yang di bawah, setelah NIK di pilih, akan muncul nama nya secara otomatis.

kemudian input nominal item barang yang ingin di beli, kemudian tekan ENTER.

Dan harga normal dari semua barang yang di beli.

Dan jika belanja lebih besar, atau sama dengan Rp.3.000.000, maka akan mendapatkan Diskon 20%. Atau di klik tombol Disk 20% d layar. Dan tampilanny(Perubahan harga setelah diskon) seperti ini,

Dan jika pembayaran pakai Card akan ditambah diskon 5%. Stelah di diskon 5% tampilannya seperti ini (perubahan harga):

Dan jika ada Voucher, harga barang akan terpotong sesuai dengan nominal Voucher ya di berikan oleh costumer, misal menggunakan Voucher 50.000, maka di klik V2 d layar, maka tampilannya akan seperti ini:

Demikian Projek ini saya buat, lebih kurangnya mohon di maklumi.

Dan saya mengharapkan kritik dan saran dari teman-teman sekalian,

terimakasih.
