Answer 1

I assume you're looking to edit the ID3 tags of an MP3 file (other formats, including MP4, usually have a different system for metadata).

Basically, you're going to want to:

• Open the MP3 file
• Read in the existing ID3 tags from the MP3 file
• Populate text views with the data
• When the user saves, write the new ID3 tags to the MP3 file.

It looks like there's a fairly old library for dealing with id3 tags in Java, so you might even save yourself a lot of effort going that route.
