GUI Problem

Question

Having a problem with jRadioButtons and an action event when a button is pushed. We want to have a calculation run when the user pushes the OK button. Need to know which radion button is selected so the calculation has the right data. Here is some of the code I have tried from other sources but can't get it to work.
/*public boolean action (Event evt, Object arg) {
if(evt.target.equals(jRadioButton7yearloan))
Calc7year();
else if(evt.target.equals(cb2))
t.setText("Radio button 2");
else if(evt.target.equals(cb3))
t.setText("Radio button 3");
else
return super.action(evt, arg);
return true;
public class RadioListener implements ActionListener
public void actionPerformed(ActionEvent e)
String factoryName = null;
if (e.getActionCommand() == seven)
Calc7year();
else{}
public void Calc7year()
double LA = Double.parseDouble(jTextFieldAmountInputBox.getText());
double IR = 0.0535;
double T = 15;
Payment = (((IR/100) / 12) * LA) / +
(1- (Math.pow (1+ ((IR/100) / 12), (T * -12))));
jTextFieldOutputCalc.setValue(Payment);
private void jButtonOK_actionPerformed(ActionEvent e)
System.out.println("\njButtonOK_actionPerformed(ActionEvent e) called.");
//jTextFieldOutputCalc.setValue(Payment);
RadioListener();
private void jButtonOK_mouseClicked(MouseEvent e)
System.out.println("\njButtonOK_mouseClicked(MouseEvent e) called.");
RadioListener();
}

When you post code use the "code" formatting tags. This link also has some further guidelines to help you get better answers.

The Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/button.html]How to Use Buttons has an example using radio buttons and a ButtonGroup that might help you.
