Hi,

You will have to use following code:

int i=JOptionPane.showConfirmDialog(null, "Really want to quit?","Really",JOptionPane.YES<em>NO</em>OPTION);
  // TODO add your handling code here:
if(i==JOptionPane.YES_OPTION)
{
    //CODE WHICH WILL BE CALLED ONCE YES IS PRESSED
}
else
{
    //CODE WHICH WILL BE CALLED ONCE NO IS PRESSED
}

You have to store the value of Joption pane in an integer which can be done from following: int i=JOptionPane.showConfirmDialog(null, "Really want to quit?","Really",JOptionPane.YESNOOPTION);

then use if (With int i) to find the answer:

if(i==JOptionPane.YES_OPTION) {

} else {

}
