i trying play audio file in background of frame window , i'm finding out way more complicated adding picture.
i found "tutorial" should how add music , seemed simple, @ least in amount of code required. however, not able play audio file, saying 2 things...
1st - trying play audio file copied java project , telling me not find file or directory.
2nd - gave method path audio file , it's telling me...
could not audio input stream input file please keep in mind i'm new , tutorial did not give lot of help, not know lot of play method doing. i'd love learn how i've seen overly complicated project , don't have time put in because it's not necessary little added flair all.
any appreciated!! put stars around code in question.

- java's audio api doesn't support (all) mp3 encoding. if need play mp3's should have @ javazoom's jlayer api
- if file trying play within project's src (or jar file extension), need use
class#getresourceorclass#getresourceasstreaminstead clipauto supports looping itself, don't need use loop of own, block event dispatching thread.- the
thread's seem little on kill imho , while still use 1 add artificial delay, used swingtimerin example, it's simpler :p
for example
