java Layout

Hi Friend,

Try the following code:

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

class LayoutExample extends JFrame{
    JPanel panel,panel1,panel2;
    JLabel lab1,lab2;
    JTextField text1,text2;
    JButton b1,b2,b3;

    LayoutExample(){
        panel=new JPanel();
        panel1=new JPanel(new GridLayout(2,2));
        panel2=new JPanel(new FlowLayout());

        lab1=new JLabel("Name");
        lab2=new JLabel("Address");

        text1=new JTextField(20);
        text2=new JTextField(20);

        b1=new JButton("Add");
        b2=new JButton("View");
        b3=new JButton("Delete");

        panel1.add(lab1);
        panel1.add(text1);
        panel1.add(lab2);
        panel1.add(text2);

        panel2.add(b1);
        panel2.add(b2);
        panel2.add(b3);

        panel.add(panel1,BorderLayout.NORTH);
        panel.add(panel2,BorderLayout.SOUTH);

        add(panel);
        setVisible(true);
        setSize(500,150);

        b1.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e){
            String v1=text1.getText();
            String v2=text2.getText();
            try{
            Class.forName("com.mysql.jdbc.Driver");
            Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
            Statement st=con.createStatement();
            int i=st.executeUpdate("insert into data(name,address) values('"+v1+"','"+v2+"')");
            JOptionPane.showMessageDialog(null,"Data is inserted successfully");
            }
            catch(Exception ex){
            }
            }
        });

        b2.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e){
            String v1=text1.getText();
            String v2=text2.getText();
            JFrame f=new JFrame();
            JLabel l1=new JLabel("Your Name is      : "+v1);
            JLabel l2=new JLabel("Your Address is : "+v2);
            l1.setBounds(20,20,200,20);
            l2.setBounds(20,50,200,20);
            f.setLayout(null);
            f.add(l1);
            f.add(l2);
            f.setVisible(true);
            f.setSize(300,200);
            }
        });

        b3.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e){
            String v1=text1.getText();
            String v2=text2.getText();
            try{
            Class.forName("com.mysql.jdbc.Driver");
            Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
            Statement st=con.createStatement();
            int i=st.executeUpdate("delete from data where name='"+v1+"' and address='"+v2+"'");
            JOptionPane.showMessageDialog(null,"Data is deleted successfully");
            }
            catch(Exception ex){
            }
            }
        });
    }
    public static void main(String[] args) 
    {
        new LayoutExample();
    }
}

Thanks
