Java regular expression – matches all strings except a few

I have these strings in the array. I want to iterate over the array and find matching data (check one row for each match)

Bird
Cat
Dog
Fish
CatDog
DogCat

Now, with regexbuddy, I have this regular expression:

(?!Cat\b)\b\w+

I want to add "dog", so try in a regular expression match and I'll get a match, you know, like an or operator I hope it can check the existence of "cat" or "dog" or "fish" at one time

Any ideas?

Solution

Try the following:

\b(?!(?:Bird|Cat|Dog|Fish|CatDog|DogCat)\b)\w+

|Character is the or operator in regular expressions
