LANGKAH-LANGKAH MEMBUAT APLIKASI DATABASE DENGAN MENAMPILKAN HASIL GRAFIK DENGAN NAMA PROJECT "SYAHENFEBFAHNA"
( APLIKASI INPUT NILAI MAHASISWA )
Hendra Supriatna (171011401082)
1. Kalian Harus Memiliki Aplikasi Neatbens java , NAVICHAT , & XAMPP
2 . Run XAMPP Terlebih Dahulu , Klik Start Pada MSYQL & APACHE
3 . Masuk Ke Navichat > Klik Connection > Pilih MYSQL
Connection Name > localhost
4 . Klik Kanan Pada LocalHost > New Database > Database Name > indexprestasi
5 . Jika Sudah Akan Muncul IndexPrestasi > Table , DataMhs , User Seperti ini
6 . Buka Neatbens , Buat New Project > Pilih Java Application > Beri Nama Bebas
7 . Lalu Klik Kanan Pada Source Package > Pilih New Package > Lalu Namakan
8 . Lalu Buatlah JFrame Form Dengan Nama LoginAdmin
Klik Kanan Pada Package > New > JFrameForm > Nama LoginAdmin
Design JFrame Fromnya Seperti ini
Masukan Source Code Pada LoginAdmin
