MEMBUAT APLIKASI TOKO MENGGUNAKAN JAVA NETBEANS DAN MYSQL
Perkenalkan dulu nama saya adalah fery febrianto lahir di MADIUN, itu saja informasi dari saya pppfff.....
Oke
sekarang kita masuk ke media pembahasan tentang aplikasi java NetBeans
dan Mysql. Kedua Aplikasi ini sangatlah berhubungan dalam pembuatan
aplikasi dan data base untuk penyimpanannya.
Maka dari itu jika
anda ingin membuat aplikasi harus sudah terinstall aplikasi NeatBeans
dan XAMPP, itu merupakan hal yang wajib.
Nah sebelum kita mengetik codingan atau lebih gampangnya mengcopy,,hahaha,.anda harus membuat data basenya dulu di php myadmin..
Buat seperti gambar dibawah ini :
Ingat Beri judul DbTokoABC, jangan sampai salah.
jika anda sudah membuat data basenya maka anda harus mengetik atau mengcopy codingan di bawah ini dan paste ke notepad atau notepad++.
