Answer 1

final JButton btn = new JButton("Click Me!");
JTextField txt = new JTextField(10);
InputMap inputMap = txt.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);
ActionMap actionMap = txt.getActionMap();
inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), 13);
actionMap.put(13, new AbstractAction()
{
    public void actionPerformed(ActionEvent e)
    {
        btn.doClick();
    }
});
