I have included my code below so you have an indication of what im doing:
import java.awt.*;
import java.awt.Graphics;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import java.util.Vector;
import java.io.*;
import java.util.Collections;
public class rightSplitPane {
private JSplitPane splitPane;
private JPanel p1, p2;
     private String tran, res, type;
     private Graphics gr;
public rightSplitPane() {         
p2 = new JPanel();
p2.setLayout(new BorderLayout());
//gr = p2.getGraphics();
//Graphics2D g2d = (Graphics2D) gr;
//gr.drawLine(30, 40, 100, 100);
     //gr.drawRect(24, 10, 60, 60);
//p2.repaint();
JScrollPane topPane = new JScrollPane();
topPane.setBorder(BorderFactory.createEmptyBorder(5,5,5,5));
topPane.getBorder();
          JScrollPane bottomPane = new JScrollPane(p2);
          bottomPane.setBorder(BorderFactory.createEmptyBorder(5,5,5,5));
bottomPane.getBorder();
//Provide minimum sizes for the two components in the split pane
Dimension size = new Dimension(625, 350);
topPane.setMinimumSize(size);
bottomPane.setMinimumSize(size);
//Create a split pane with the two scroll panes in it
splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT, topPane, bottomPane);
splitPane.setOneTouchExpandable(true);
splitPane.setDividerLocation(350);
topPane.getViewport().add(trTable, BorderLayout.CENTER);
public JSplitPane getSplitPane() {
return splitPane;
     public static void main(String args[]) {
          rightSplitPane test = new rightSplitPane();
//HOW DO I GET THE SPLITPANE TO BE DISPLAYED TOO??
} // end class

public JSplitPane getSplitPane()
     return splitPane;
public static void main(String args[])
     rightSplitPane test = new rightSplitPane();
     JFrame frame = new JFrame();
     frame.setSize(700,500);
     frame.setContentPane(test.getSplitPane());
     frame.setVisible(true);
