Why does this not work? It gives me a NullPointerException?

    where is your audio file placed? – jmj Jun 27 '14 at 19:48

    Here is a clue: the exception includes a line number. look on that line or tell us the line number and indicate which line it is in your included code. – DwB Jun 27 '14 at 19:48
  • I'm assuming the error is at `as1 = AudioSystem.getAudioInputStream...`, since the file path is probably wrong. Where is your `.wav` file located? – tcooc Jun 27 '14 at 19:52

I found out why it wasn't working! I had put "/" before 'res/music.wav' which caused the file loading system to think I was loading from a DRIVE (eg C:/ F:/), but there was nothing before that / so it thought it was loading from a null drive, which cannot exist.
