How to align JLabel-JTextField pairs vertically

Question

What I mean by a JLabel-JTextField pair is a JLabel component followed by a JTextField one, for example, \"Parameter 1: -----\" where \"-----\" denotes a blank JTextField.

Answer 1

You didn't specify which layout do you use, so a good layout to implement that would be GridBagLayout. The demo in oracle site is great to start with.

And a short example:

JPanel panel = new JPanel();
panel.setLayout(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 0;
panel.add(new JLabel("Label 1:"), c);
c.gridx = 1;
c.gridy = 0;
panel.add(new JTextField("TextField 1"), c);
c.gridx = 0;
c.gridy = 1;
panel.add(new JLabel("Label 2:"), c);
c.gridx = 1;
c.gridy = 1;
panel.add(new JTextField("TextField 2"), c);
