What is not working?its not working
Add some println() statements to both the if and the else parts and see which is being executed.

Re: if and else
I'm not very good at RadioButtons as I haven't really used them, but would this help:Originally Posted by AbdulAziz Bader
if(JRadioButton1.isSelected() == true)
Also, why are you setting the text of JLabel to both "right" and null?
That will just set it to null.
Try this:
if (jRadioButton1.isSelected()) == true) { // jLabel2.setText("right"); // jLabel2.setText(null); buttonGroup1.clearSelection(); jLabel1.setText("how old am I"); jRadioButton1.setText("15"); jRadioButton2.setText("16"); jRadioButton3.setText("17"); jRadioButton4.setText("18"); } else jLabel2.setText("wrong"); or this, depending on which one you're looking for. if (jRadioButton1.isSelected()) == true) { jLabel2.setText("right"); // jLabel2.setText(null); // buttonGroup1.clearSelection(); jLabel1.setText("how old am I"); jRadioButton1.setText("15"); jRadioButton2.setText("16"); jRadioButton3.setText("17"); jRadioButton4.setText("18"); } else jLabel2.setText("wrong");

Re: if and else
That's just ... silly. The if statement requires a boolean condition, which isSelected() already returns.
It is NEVER required to compare a boolean with true or false.

Re: if and else
Chances are you have more than one variable with the same name: the one an instance field, the other a method local variable that hides it.
To get better help sooner, post a SSCCE. <== link

Re: if and else
you have to try remove method to clear it and then call revalidate(); method to refresh your page (it depends on your whole code of course )
Re: if and else
The question was about clearing the selection in a ButtonGroup, not about removing components from a visible GUI.

Re: if and else
I meant that you have to remove a specific component by using component's remove methodThe question was about clearing the selection in a ButtonGroup, not about removing components from a visible GUI.
I mention that it depends on the whole code to do it!!
Re: if and else
So you answered a question other than the one asked. That must have been helpful!
