You can write to/from the system clipboard in Java. For example;

1. Reading from the system clipboard

Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
Transferable contents = clipboard.getContents(null);
String buf;
if ((contents != null) && contents.isDataFlavorSupported(DataFlavor.stringFlavor))
{
 try 
     {
  buf=(String)contents.getTransferData(DataFlavor.stringFlavor);
     }
 catch (Exception e) {e.printStackTrace();}   
}

2. Writing to the system clipboard

Transferable contents = clipboard.getContents(null);
if ((contents != null) && contents.isDataFlavorSupported(DataFlavor.stringFlavor))
