Question

I want to make a paste from the system clipboard in java. How would I do this?

Answer 1

Try this

public static void type(String characters) {
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
StringSelection stringSelection = new StringSelection( characters );
clipboard.setContents(stringSelection, instance);
//control+V is for pasting...
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
}

Answer 2

You could also try using the Clipboard class.

Answer 3

You could use the robot class like this

try
{
    Robot r = new Robot();
    r.keyPress(KeyEvent.VK_CONTROL);
    r.keyPress(KeyEvent.VK_V);
    r.keyRelease(KeyEvent.VK_CONTROL);
    r.keyRelease(KeyEvent.VK_V);

}
catch(Exception e)
{

}

Answer 4

You have to use Java graphics library, eg. take a look at http://download.oracle.com/javase/1,5.0/docs/api/java/awt/datatransfer/Clipboard.html

Answer 5

While the robot class would work, it's not as elegant as using the system clipboard directly, like this:

private void onPaste(){
    Clipboard c = Toolkit.getDefaultToolkit().getSystemClipboard();
    Transferable t = c.getContents(this);
    if (t == null)
        return;
    try {
        jtxtfield.setText((String) t.getTransferData(DataFlavor.stringFlavor));
    } catch (Exception e){
        e.printStackTrace();
    }//try
}//onPaste
