Java Regular Expressions Help

[Lee]

Hi there,

I wonder if anyone can tell me how to set a boolean if I encounter a
word in a string (in upper, lower, or a combination of cases) e.g. I
want to set a boolean to true if either "hello", "HELLO", or "hElLo" is
found in "Hello there!".

So far, I have

Pattern p = Pattern.compile("HELLO");
Matcher m = p.matcher("HELLO there!");
myBoolean = m.lookingAt();

Can anyone tell me how to modify the above so that is will match true
for upper/lower case, and will return true even in the case:
" 4HELLO123"


Stumped!!!

Thanks,
Lee

Pattern p = Pattern.compile("HELLO", Pattern.CASE_INSENSITIVE);

To match a substring, use find() instead of lookingAt() or matches().
