Membuat Aplikasi CRUD Sederhana Menggunakan Java Netbeans
Selamat datang di blog Mari belajar coding. Kali ini kita kembali lagi belajar pemrograman java menggunakan NetBeans IDE. Jika tutorial sebelumnya kita pernah belajar membuat koneksi database antara mysql dengan java, tutorial ini kita akan belajar bagaimana membuat sebuah aplikasi desktop menggunakan java NetBeans untuk menyimpan mengubah menghapus dan menampilkan data ke tabel dari database mysql ke GUI NetBeans.
Pertama-tama buat database mysql. Dalam tutorial membuat aplikasi Crud java Netbeans, kita akan menggunakan database bernama penjualan dengan satu tabel bernama produk.
CREATE DATABASE `penjualan`;
USE `penjualan`;
CREATE TABLE `produk` (
`IDProduk` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
`KodeProduk` varchar(32) UNIQUE KEY,
`NamaProduk` varchar(255),
`Satuan` varchar(255),
`Harga` int(11),
`Stok` int(11) ,
`CreateDate` datetime
);
Setelah database dibuat, selanjutnya buka aplikasi NetBeans IDE kemudian buat projek baru bernama Penjualan.
File->New Project->Java Application
Klik kanan pada Package Penjualan, buat file java class bernama koneksi untuk menghubungkan aplikasi yang akan kita buat dengan database penjualan.
File koneksi.java seperti dibawah ini.

public class koneksi {
private static Connection KoneksiDatabse;
public static Connection koneksiDB() throws SQLException {
try {
String DB ="jdbc:mysql://localhost/penjualan";
String user="root";
String pass="";
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
KoneksiDatabse = (Connection) DriverManager.getConnection(DB,user,pass);
} catch (Exception e) {
JOptionPane.showMessageDialog(null,"Tidak ada koneksi","Error",
JOptionPane.INFORMATION_MESSAGE);
System.err.println(e.getMessage());
System.exit(0);
}
return KoneksiDatabse;
}
}
Tambahkan library MySQL JDBC Driver, klik kanan pada folder libraries kemudian pilih add library.
Buat Interface GUI untuk menampilkan form produk dan tabel produk dengan cara klik kanan pada package Penjualan->New->JFrame Form.
Buat Interface GUI untuk menampilkan form produk dan tabel produk dengan cara klik kanan pada package Penjualan->New->JFrame Form.
Simpan dengan nama class produk. Kemudian buat layout seperti gambar dibawah ini.
Keterangan:
Untuk membuat header dan keterangan inputan form, pilih Label pada bagian Pallete di sisi kanan layout.
Untuk membuat inputan form, pilih textfield kecuali pada inputan Satuan pilih yang combobox.
Untuk menambah item select pada combobox, klik kanan kemudian pilih properties->model
Ganti variabel name setiap textfield, combobox, button, dan tabel dengan cara klik kanan pilih Change Variabel Name.
File produk.java seperti dibawah ini.
