As for actually figuring out the import, I won't comment on that.

Let's just assume we have find_import.sh which takes one argument  
(class name) and returns the actual import statement.

Then to use it, you could do something like:

  1) place caret on class name (no need to select it)
  2) Automation / Start Macro Recording
  3) Text / Filter Through Command
      a) set command to: find_import.sh "$TM_CURRENT_WORD"
      b) set input to: none (doesn't really matter)
      c) set output to: Place on clipboard
  4) Move to begin of document (cmd arrow up)
  5) Edit / Find / Find…
      a) set Find string to: ^(?=@import) or whatever you use in Java :)
      b) enable regular expression check box
      c) press next (should find first @import statement and close  
dialog)
  6) Edit / Paste (i.e. the import line returned from the script)
  7) Automation / Stop Macro Recording

Now you can save the macro and use later.

I made it a regexp search only to not have the find actually select  
the stuff found (by using look-ahead).

And would be pretty tied to Java ;) so no, that's not possible.
