Here is an example:

  import java.awt.*;
  import java.awt.event.*;
  import com.sun.java.swing.*;
  import java.awt.datatransfer.*;
  import java.io.IOException;
  public class ClipIt {
    public static void main (String args[]) {
    final Clipboard clipboard =
      Toolkit.getDefaultToolkit().getSystemClipboard();
    JFrame f = new JFrame ("Clip It");
    f.addWindowListener (new WindowAdapter() {
      public void windowClosing (WindowEvent e) {
        System.exit (0);
      }
    });
    Container c = f.getContentPane();
    final JTextArea jt = new JTextArea();
    JScrollPane pane = new JScrollPane (jt);
    c.add (pane, BorderLayout.CENTER); 
    JButton copy = new JButton ("Copy");
    copy.addActionListener (new ActionListener() {
      public void actionPerformed (ActionEvent e) {
        String selection = jt.getSelectedText();
        StringSelection data = new StringSelection(
         selection);
        clipboard.setContents (data, data);
      }
    });
    JButton paste = new JButton ("Paste");
    paste.addActionListener (new ActionListener() {
      public void actionPerformed (ActionEvent e) {
        Transferable clipData = clipboard.getContents
         (clipboard);
        if (clipData != null) {
          try {
            String s = (String)(clipData.getTransferData
             (
              DataFlavor.stringFlavor));
            jt.replaceSelection (s);
          } catch (UnsupportedFlavorException ee) {
            System.err.println ("Unsupported flavor: 
             " + ee);
          } catch (IOException ee) {
            System.err.println ("Unable to get data: 
             " + ee);
          }
        }
      }
    });
    JPanel p = new JPanel();
    p.add (copy);
    p.add (paste);
    c.add (p, BorderLayout.SOUTH);
    f.setSize (300, 300);
    f.setVisible (true);
  }
}

NOTE:
Java does not currently support pasting objects like images from external applications. You could copy an ImageIcon and treat it as a javaSerializedObjectMimeType. However, it would then only be pasteable into another Java program, or a program that understands Java's serialization mechanism, which will be described in the "Object Persistence and Serialization" section of Chapter 19.
