Membuat Koneksi Mysql Menggunakan Java Script

Membuat koneksi dengan script java akan membuat atau menyambungkan data yang ada pada Mysql akan terditeksi, dengan bantuan XAMPP semuanya akan jadi mudah memasukan dan menghapus data, beberapa contoh Script java coneksi dibawah ini akan membantu anda membuat data di mysql.

2. Script Menu

import javax.swing.*;


public class menu extends JFrame {


    JMenuBar menubar = new JMenuBar();
    JMenu file = new JMenu("File");
    JMenu operasi = new JMenu("Operasi");
    JMenu about = new JMenu("Pembuat");
    JMenuItem exit = new JMenuItem("Exit");

    menu() {
        setTitle("Contoh Menu ");
        setLocation(400, 200);
        setSize(400, 250);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);


    }


    void pengaturanComponen() {
        getContentPane().setLayout(null);


        menubar.add(file);
        menubar.add(operasi);
        menubar.add(about);
        file.add(exit);
        operasi.add(cruid);

        getContentPane().add(menubar);
        menubar.setBounds(4, 4, 400, 40);
        setVisible(true);
    }


    void aksi() {
        exit.addActionListener(new java.awt.event.ActionListener() {


            public void actionPerformed(java.awt.event.ActionEvent evt) {


            System.exit(0);


            }

    public static void main(String[] args) {




        menu runningapp = new menu();
        runningapp.pengaturanComponen();
        runningapp.aksi();
    }
}




3. Script koneksi

import javax.swing.*;
import java.awt.*;
import java.sql.*;
public class Koneksi {
    
    void koneksiDatabase(){
            try {
             Class.forName("com.mysql.jdbc.Driver");
           Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/dbnews?user=root&password=");
           Statement stmt = conn.createStatement();
           
        } catch (SQLException ex) {
            JOptionPane.showMessageDialog(null, ex.getMessage());
        } catch (ClassNotFoundException ex) {
            JOptionPane.showMessageDialog(null, ex.getMessage());
        }


    }






    public static void main(String args[]){
    Koneksi kon=new Koneksi();
    kon.koneksiDatabase();


    }






}
4. script import

apabila ingin menambahkan foto dalam data maka scriptnya

import javax.swing.*;




class About extends JFrame {


 JLabel lblFoto =new JLabel();
 JLabel Ket =new JLabel("Created By: ");


 About (){
  setTitle("About..");
  setLocation (200,300);
  setSize(200,200);
  setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
aturKomponen();
  setVisible(true);
 }


 void aturKomponen(){
 lblFoto.setIcon(new javax.swing.ImageIcon("edit.png"));


  getContentPane().setLayout(null);
  getContentPane().add(lblFoto);
  lblFoto.setBounds(50,20,200,180);
  getContentPane().add(Ket);
  Ket.setBounds(10,40,200,20);
 }




 public static void main(String args[]){


  java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new About().setVisible(true);
            }
        });




 }
}
