Split pane into two halves using Swing

Can anyone suggest me how can I divide my JTabbedPane in two equal horizontal sections? My Pane has three tabs in it. I want to divide the second tab pane (tab 2) into two equal halves?

Code for Tabbed Pane

import javax.swing.*;
import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JSplitPane;

public class Monitor{
  public static void main(String[] args){
  JFrame frame = new JFrame("WELCOME");
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  JTabbedPane tab = new JTabbedPane();
  frame.add(tab, BorderLayout.CENTER);
  JButton button = new JButton("1");
  tab.add("tab1", button);
  button = new JButton("2");
  tab.add("tab2", button);
  button = new JButton("3");
  tab.add("tab3", button);
  frame.setSize(400,400);
  frame.setVisible(true);

  }
}

Use a single row GridLayout for the JPanel that is placed in that tab. With two components in it, they will each have half the space. E.G.

enter image description here

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

public class Monitor {

    public static void main(String[] args){
        Runnable r = new Runnable() {
            public void run() {
                JFrame frame = new JFrame("WELCOME");
                // A better close operation..
                frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
                JTabbedPane tab = new JTabbedPane();
                frame.add(tab, BorderLayout.CENTER);
                JButton button = new JButton("1");
                tab.add("tab1", button);

                // this GridLayout will create a single row of components,
                // with equal space for each component
                JPanel tab2Panel = new JPanel(new GridLayout(1,0));
                button = new JButton("2");
                tab2Panel.add(button);
                tab2Panel.add(new JButton("long name to stretch frame"));
                // add the panel containing two buttons to the tab
                tab.add("tab2", tab2Panel);

                button = new JButton("3");
                tab.add("tab3", button);
                // a better sizing method..
                //frame.setSize(400,400);
                frame.pack();
                frame.setVisible(true);
            }
        };
        SwingUtilities.invokeLater(r);
    }
}
