My code is:
Pattern pattern = Pattern.compile("[A|AB|ABC]");
Matcher matcher = pattern.matcher("ABC");
System.out.println(matcher.group());`
The Stdout output is: A
But I want it to print "ABC" since ABC is the longest match.

2Order of options matters. Reverse the order: `ABC|AB|A` or use `AB?C?` – ctwheels Dec 08 '17 at 20:15

2Don't put it in `[]`. `[]` is a set, which, in your case, is saying *match a character present in the set `A|BC` because it's those characters literally – ctwheels Dec 08 '17 at 20:18

You'll want to use [greedy quantifiers](https://stackoverflow.com/questions/5319840/greedy-vs-reluctant-vs-possessive-quantifiers). – John Ellmore Dec 08 '17 at 20:19

There was a typo in my original code. ctwheels was correct. The order matters. Thanks! – user2922049 Dec 08 '17 at 20:23
