Problems with Timer Constructor
Hi there. I am a student at uni who is doing a a few java topics. I have been asked to create a gui which represents a microwave. I have set the interface and gotten the buttons to respond by using a listener. However I keep having trouble trying to initiate a timer. I get this error message:
Symbol: Constructor Timer(int, microwave.Contents.ButtonListener)
Location: Class java.util.Timer
Here is my code.

package microwave;

I am using a netbeans IDE. Is there any reason I am getting this message. What do I seem to be missing?
