Best Way to Check for same Word in string?

Feb 6th, 2005

Is the best way to check for 2 words of same type in a string to make a stringtokenizer and story every word in an array then compare it in a for loop?
seems like a hassle for comparing for same words i was wondering if theres a better way?

String has a split function that's more efficient than StringTokenizer.
But for your problem take a look at regular expressions, they were invented for things like that.
There's a set of functions "indexOf" in String which you can use to look for the starting index of a substring in a string.

you could always use this:

boolean equalsIgnoreCase(String anotherString);

No, that compares two Strings. Here the problem is to detect whether a single word is repeated several times inside a single String.

this thread is two years old, why not post in another topic? many people also frown upon thread hijacking
