Hi Friend,

We have modified your code, there were many errors.Try this:

import java.sql.*;
import javax.swing.*;
import java.awt.event.*;;

public class NewJFrame extends JFrame {
Connection con=null; 
Statement st=null;
ResultSet rs=null;

public NewJFrame() {
    initComponents();
}
private void initComponents() {
setLayout(null);
JButton b=new JButton("Retrieve");
b.setBounds(10,10,100,20);
add(b);
setSize(300,100);
setVisible(true);

b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent evt) {
        try{
        Class.forName("com.mysql.jdbc.Driver");
        con=DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","root");
        st=con.createStatement();
        String query="SELECT * FROM employee";
        rs=st.executeQuery(query);
        int count=0;
        while(rs.next()){
            String n=rs.getString("name");
            String b=rs.getString("address");
            String s=rs.getString("contactNo");
            String t=rs.getString("email");
            System.out.println(n+" "+b+" "+s+" "+t);
            count++;
            }
            if(count<0){
            JOptionPane.showMessageDialog(null,"no record");
            }
        }
        catch(Exception e) {
        JOptionPane.showMessageDialog(null,"error"); 
        }
    }
});
}
public static void main(String[]args){
    new NewJFrame();
}
}
