I need a little help .....
I have a problem with the method showMessageDialog belonging to JOptionPane's class.
I used this method to menage an event (in particular a button event). This is the code I used:
public void actionPerformed(ActionEvent e)
if (e.getActionCommand() == "View")
String output = "Credits: " + "200" ;
JOptionPane.showMessageDialog(null, output , "Status", JOptionPane.INFORMATION_MESSAGE);
The result is an empty pane with the only button "OK".
Neither the String I passed as parameter nor the icon "I" (because it is an INFORMATION_MESSAGE the icon is just an "I") was displayed....
So I tried to run the exclusive JOptionPane.showMessageDialog code in another new file and it works correctly....
What do I wrong?
Thanks for your support.
