Regex question

[Max Power]

hi, i am trying to build a regex that matches this string:

something[\^]something or something\^something

i tried something like this: .*(\\[)?\\^(\\])?.* but thats not working....

any ideas?
thanks

this seems to do it:

    String s1 = "something[\\^]something";
    String s2 = "something\\^something";
    String s3 = "somethingsomething";
    String regex = ".*\\[?\\\\\\^\\]?.*";
    
    System.out.println( s1.matches( regex ) );
    System.out.println( s2.matches( regex ) );
    System.out.println( s3.matches( regex ) );

output:
true
true
false

Note that this will also match

something[\^something

and

something\^]something

If that's not cool, try

String regex = ".*(\\\\\\^|\\[\\\\\\^\\]).*";

I haven't tried it though, but it seems reasonable given Ray's test cases.
