You can say I am somewhat lazy. hehehehe I think of all the Java String operations I've tested, indexOf is nether the slowest, nor the fastest, clocking in at 15 miliseconds.  To contrast, String.equalsIgnoreCase is a hog, at 28 miliseconds, and String.equals is an acceptable 7 miliseconds, which is still far away from the coveted int == int is only 3 miliseconds.  (on my test strings, your results will vary).

Perhaps counting the number of commata up to the index position ( found by String.indexOf(String)  ) in the string might help. sincerely, U.
