单击按钮以打开新的JFrame

Question

Im currently working on an aplication on Eclipse and what I need is to press a button and then a JFrame to open, containing values from MySQL DB on a JTable. I had recently asked a question here about an error I had in trying to show columns using absolute layout(null layout) and I was told that it would be preferable to use layouts. The thing is that i have multiple buttons and stuff on my existing form and changing the layout would hide some of the features and I couldn't find a solution.So I thought of something. Since the JTable has issues with absolute layout and Layout Managers dont help me with my multiple buttons, I could delete the JTable from my existing form(null layout) and keep the buttons. As a result, when a user presses the "Sort by Name" or "Add Console" buttons I have for mySQL app on the existing form, then a new JFrame should pop up and show the correct JTable. Is there a possible way to do that?

JTable Creation Process :

 package newWindow;

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

 public class newWindow {

 public static void main(String[] args) {
    new newWindow();
   }

 public newWindow() {
   EventQueue.invokeLater(new Runnable() {
       @Override
         public void run() {
           try {
 UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
 } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {}

  try
  {
  Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/test1?user=mySQL&password=7777");
  Statement stmt = conn.createStatement();
  ResultSet rs = stmt.executeQuery("SELECT * FROM consoles INNER JOIN hardware ON consoles.id=hardware.id");
  ResultSetMetaData md = rs.getMetaData();
  int columnCount = md.getColumnCount();
  String[] cols = new String[columnCount];
  int i;
  for (i=1;i<= columnCount;i++)
   {
     cols[i-1] = md.getColumnName(i);
   }
   DefaultTableModel model = new DefaultTableModel(cols,0);
     while (rs.next())
       {
         Object[] row = new Object[columnCount];
             for (i = 1 ; i <= columnCount ; i++)
                 {
                   row[i-1] = rs.getObject(i);
                 }
      model.addRow(row);
        }
   JFrame frame = new JFrame("Promitheas");
   JTable table = new JTable(model);
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   frame.getContentPane().setLayout(new GridLayout());
   JScrollPane scrollPane = new JScrollPane(table);
   frame.getContentPane().add(scrollPane);
   frame.pack();
   frame.setLocationRelativeTo(null);
   frame.setVisible(true);
   conn.close();
   stmt.close();
   rs.close();
  } catch (SQLException case1) { case1.printStackTrace();
  } catch (Exception case2) { case2.printStackTrace();}               
    }
  });
 }
}

Sort by Name Button :

try{
   conn = DriverManager.getConnection("jdbc:mysql://localhost/test1?user=mySQL&password=7777");
   String[] gender = { "ASC", "DESC"};
   int response = JOptionPane.showOptionDialog(null,"Ascending or Descending Order?","Make a choice...",0,JOptionPane.INFORMATION_MESSAGE,null,gender,gender[0]);
   stmtsortname = conn.createStatement();
   String sql = null;
   if (response == JOptionPane.YES_OPTION)
        sql = "ASC";
   if (response == JOptionPane.NO_OPTION)
        sql = "DESC";
  rssortname = stmtsortname.executeQuery("SELECT * FROM consoles INNER JOIN hardware ON consoles.id=hardware.id ORDER BY consoles.name "+sql);
                              .
                              .
                              . 
             create an newJTable overwriting the old
                              .
                              .
 } catch ...  

Answer 1

Make a class which takes the data you want transfered as a parameter. Do your magic setup the table and set visible true and replace blala with your logic

public class NewJFrame extends JFrame{

   public NewJFrame(Data data){
      blala
      this.setVisible(true);
   }
}

and then on the button you have the ActionListner or something simmilar in that

new NewJFrame(data);
