String split with stringtokenizer

Question

I have a string which is like

"AB-123,XYZ-456,AB-11,AB-3423,XYZ-1"

I want to separate out all AB's in one string and XYZ in another. I can do it using stringtokenizer and match the AB's and XYZ and build tow new strings out of it, is there a better way to achieve this.

Thanks.

a better way in what sense? Is your current way not working, inefficient, hard to read, etc.? — dMb

I would personally split the two tasks:

Split the single string into a list / array / whatever
Go through the results and add the strings to one result list or the other

These are logically independent steps, and I think your code will be clearer if you treat them separately. You should also consider what you want to happen if one of the parts doesn't start with either AB or XYZ.

For the splitting part, you could either use String.split or Guava's Splitter class.

String.split and Guava'splitter,which is better?I mean easier to use with more beautiful code style?
@chance: Well if you're going to split in the same way in multiple places, I'd definitely use Splitter. For a one off, String.split is okay...
