can i use requestFocus

[jwxie]

I am given an assignment but I am totally new to Java (i have been programming in C++ and Python for two years).

So we are doing GUI and basically we extended JFrame and added a couple fields.

Say we have a field named "Text 1" and "Text 2". When user press enter with the cursor in Text 1, move the focus to Text 2. I tried to add

	private JTextField textfield1() {
		textfield1 = new JTextField();
		textfield1.setPreferredSize(new Dimension(200, 20));
		textfield1.addActionListener(
				new ActionListener() {
					public void actionPerformed(ActionEvent e) {
						textfield1text = textfield1.getText().trim();
						textfield1.setText(textfield1text);
						System.out.println(textfield1text);

						textfield1.requestFocus();
					}
				});
return textfield1;

But that doesn't work at all.
I noticed that requestFocus is not recommended, and instead one should use requestFocusWindows. But I tried that too. Upon some readings it seems like I have to do keyboard action & listener??? But my teacher said it only requires 1 line....

ANy help is appreciated.
