Dynamically changing the title of a final JRadioButton

Question

I'm having this problem where I can't figure out how to update the name of my JRadioButtons

I've set them up in the contsructor like so:

final JRadioButton ANSWER1 = new JRadioButton(answer1);

with answer1 being a String.

but whenever i change answer1, the name of the JRadioButton doesn't change.

I've set the JRadioButton to change name at the event of a JButton being clicked:

NEXT.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
    qnumber++;
    answer1 = "blah blah";
    ANSWER1.setText(answer1);

but this doesn't seem to have any effect, any help would be greatly appreciated, thanks.

Can you post the full code for this? Also, make sure you're getting into that `actionPerformed` method by placing a breakpoint. — Stefan, Apr 03 '14 at 08:35
What you think you're changing is what you actually want to change — MadProgrammer, Apr 03 '14 at 08:36

final JRadioButton ANSWER1 = new JRadioButton(answer1);

should be (search for Java naming conventions)

final JRadioButton answer1 = new JRadioButton(ANSWER1);

whatever hidden in String value answer1 (this variable should be defined as constant - private String ANSWER1) can be used for setName, setActionCommand, putClientProperty or descriptor for Swing Action, you can returns this value from every AWT/Swing Listeners added to JRadioButton

use JLabel for displaying narrative on the screen, you can to chains the JLabel with JRadioButton by using setLabelFor

use ItemListener for JRadioButton, test for SELECTED/DESELECTED instead of ActionListener
