How to use contains() with a char?

Question

I'm trying to use the contains method on a string with a single character that i'm supplying. Is there any easy way to do this that i might not be thinking of? or do i have to go through a series of weird casts to get a CharSequence object?

Answer 1

contains(str) is the same as indexOf(str) != -1, but indexOf() also have an overload taking a char, so use indexOf(ch) != -1.
