Where in your code is the problem? Please add some comments to the code that show where the problem is.

There is one and only 1 if...else statement in there:

Code :

---

 if (jRadioButton1.isSelected())
      { jLabel2.setText("right");}
      else jLabel2.setText("wrong");

---

and there is nothing wrong with that.

However this looks like IDE generated code. Either don't mess with it and accept it, or erase and start writing
