Java Mysql simple project in Eclipse

This JDBC will teach you how to do the search in Eclipse using Mysql Database.

First Step :  Establish the database connection in order to connect java and mysql. i attached the code below.

Connection con;
PreparedStatement pst;
public void Connect()
    {
        try 
        {
            Class.forName("com.mysql.jdbc.Driver");
            con = DriverManager.getConnection("jdbc:mysql://localhost/bill", "root","");
        }
        catch (ClassNotFoundException ex) 
        {
          ex.printStackTrace();
        }
        catch (SQLException ex) 
        {
          ex.printStackTrace();
        }

    }

after Established the database connection call the connect() method inside the constructor of class.

        public Seach() 
        {
  initialize();
  Connect();
 }

After done the connection part. select the find button.paste the following code inside the  addActionListener of the find button

public void actionPerformed(ActionEvent e)
 {
    
    String Billno = txtbno.getText();
    
  try 
                   {
      pst = con.prepareStatement("SELECT name,balance from purchase where id=?");
      pst.setString(1,Billno);
     
      ResultSet rs1=pst.executeQuery();

      if(rs1.next()==false)
       {
   JOptionPane.showMessageDialog(null,"Bill not found!");
   txtname.setText("");
   txtbal.setText("");
   txtbno.requestFocus(); 
        }
   else
   {
   String name = rs1.getString(1);
   String balance = rs1.getString(2);
   txtname.setText(name.trim());
   txtbal.setText(balance);
     
          }
   } 
                        catch (SQLException e1) 
                        {
