Java Reg-Ex pattern of stringA OR stringB [duplicate]

Question

So I know that pattern compilation for regular expression in java has OR statement of characters, like [abc] means 'a' or 'b' or 'c', but is there any way of saying

"helloWorld" or "goodbyeEveryone"?

Thanks a lot in advance.

How do you know what a character class is but not alternation? I thought 'alternation' came before character class in the beginners guide. — user557597

Yes. The regex would be "helloWorld|goodbyeEveryone"

The | symbol is basically the "or" operator in regex
