Theory Question on reusing an object

Question

Hi,
I am building a test question program. I have an object called TestQuestion that I would like to reuse by changing the text of the labels for every different question.
I know that I can send arguments when I call or instantiate this object in my Interface class. But is there another way? What I mean is there a way to have all of the text for the questions located in separate methods within the TestQuestion class and then have the Interface send one command to pick and choose what question?
public class Interface extends JFrame {     // 300
     static JPanel frameForCardPane;
     static CardLayout cardPane;
     private static JTextArea msgout;
     Interface () {     // 100
          super("This is a JFrame");
        setSize(800, 400);  // width, height
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          TestQuestionOne cardOne = new TestQuestionOne(msgout);
public class TestQuestion extends JPanel {
    JLabel answerTextA;
    void buildConstraints(GridBagConstraints gbc, int gx, int gy,
        int gw, int gh, int wx, int wy) {
        gbc.gridx = gx;
        gbc.gridy = gy;
        gbc.gridwidth = gw;
        gbc.gridheight = gh;
        gbc.weightx = wx;
        gbc.weighty = wy;
    public TestQuestion(JTextArea msgout) {
      // set up layout
      GridBagLayout gridBag = new GridBagLayout();
      GridBagConstraints constraints = new GridBagConstraints();
      setLayout(gridBag);
       // answer A
      buildConstraints(constraints, 1, 0, 1, 1, 30, 5); // gx, gy, gw, gh, weightx, weighty
      answerTextA = new JLabel("This is where I want to change the text!");
       constraints.fill = GridBagConstraints.NONE;
       constraints.anchor = GridBagConstraints.WEST;
       gridBag.setConstraints(answerTextA, constraints);
      add(answerTextA);
      // answer B
      buildConstraints(constraints, 1, 1, 1, 1, 30, 5); // gx, gy, gw, gh, weightx, weighty
      JButton answerTextB = new JButton("Answer B");
       constraints.fill = GridBagConstraints.NONE;
       constraints.anchor = GridBagConstraints.WEST;
      gridBag.setConstraints(answerTextB, constraints);
      add(answerTextB);
      // answer C
      buildConstraints(constraints, 1, 2, 1, 1, 30, 5); // gx, gy, gw, gh, weightx, weighty
      JButton answerTextC = new JButton("Answer C");
       constraints.fill = GridBagConstraints.NONE;
       constraints.anchor = GridBagConstraints.WEST;
      gridBag.setConstraints(answerTextC, constraints);
      add(answerTextC);
      setVisible(true);
}

Mixing the data question data in with the question display class would generally be poor design.
It would mean that anytime anyone wanted to add another question they would have to have access to the source code of your TestQuestion class and would need to recompile it.
I'd also suggest that passing in a whole JTextArea just to describe the question text is overkill. Wouldn't a String do just as well?
