You can use a Scanner or the String.split() function.

"\t" is the tab character.

it works with 1 part, but when i put it into an arraylist, it wont compile

  1. for (int i = 0; i<FileList.size(); i++)
  2. {
  3.  
  4. System.out.println(FileList.get(i).split("\t"));
  5. }

Well, I would imagine it told you why as well, rather than simply stating "This won't compile".
