How can I resize a JFrame ,to fit into the screen size

Question

I have a Jframe which has JPanel and JPanel contains lot of other components.JPanel size is 980,1400. when i use JFrame.show method jpanel goes beyond the screen size in length and I am not able to see the portion below the screen.How can I resize the JFrame so that JFrame and JPanel shrinks to fit into the screen size.I need this because I have a PRINT button at bottom of the JPanel.Thanks.

Thank you for your reply.I tried with the following code as you have told.But the frame is still going beyond the screen.Can you please look into it and tell me whats wrong ?
//public class PlayerRegForm extends javax.swing.JFrame implements Printable
public static void main(String args[]) {
PlayerRegForm prf = new PlayerRegForm();
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension frameSize = prf.getSize();
if (frameSize.height > screenSize.height)
frameSize.height = screenSize.height;
if (frameSize.width > screenSize.width)
frameSize.width = screenSize.width;
System.out.println("Screen Size ----------------- " + screenSize);
System.out.println(" Frame Size ----------------- " + frameSize);
prf.setSize(frameSize.width, frameSize.height);
prf.pack();
prf.show();
=============================================================================
Screen Size ----------------- java.awt.Dimension[width=1024,height=768]
Frame Size ----------------- java.awt.Dimension[width=112,height=28]
