Hi all,

Wondered if anyone had ever come across this problem...

I'm working my way through the Head First Java book, and am putting together the music player. Reached the third part of that, combining blobs and music. what I've found is that I get no sound (yep I have checked the volume . Also I only get a window and no blobs. When I use the downloaded code I get the blobs but still no music. I'm puzzled as I can't see any obvious typos in my code, included below in case you guys can.

Cheers,
Pete.

This is a bad idea:
} catch (Exception e) { }

How will you know if there are problems? At least print something to the console.

I compiled this same text and ran it. I was getting the music but a blank frame.

I wrote a program for this on my own with frequent updates from the book - without copying directly- and i get music with a single rectange that does not change with the note.

Some technical guru ought to guide us to find the problem. Anyone??

I'm guessing this is all old news, but you may want to try to change the paintComponent lines to:


I just compiled and ran a slightly different version and it all seems to work fine. If you'd like to try it I will post it below.
Did the first two iterations work on the command line? I'm just learning also, but hopefully this will help.
I added a little code to the catch statements also.

I was also having the closing problem as discussed in some other forum topics, and so add an EXIT_ON_CLOSE statement to the setUpGui method.

Good Luck,
Matt
