asking user to make choice through menu
I want to create a menu using JOPtionpane and ask the user to input a filename eg - music.mp3.
I want to check if the file exists and if not let the user know and get them to retry.
If it does exist I want to ask them through a menu to choose 1 of 3 options to manipulae that file. I want this choice to be made by accepting a choosen number.
If they choose one I want to reverse that music file.
If they choose two I want to loop the music file
if they choose three I want them to mix the music file.
I then want to output that file to them.
Any help .... please ... please .... please
