How to automatically focus JTextField?

Question

Right now im making a small commander with a JTextField as inputField. How do I automatically focus this when the window opens?

There is nothing else to do than inserting something into the field and pressing Enter at the end.

You need:

JFrame frame = new JFrame();
        JTextField text = new JTextField();
        frame.add(text);
        frame.addWindowListener(new WindowAdapter() {
            @Override
            public void windowOpened(WindowEvent e) {
                text.requestDefaultFocus();
            }
        });
