Question

what is the pattern to validate the following regular expression in java.
string with only letters, spaces and apostrophes (‘)

I know that for letters is this ("^[a-zA-Z]+$")
For spaces is this ("\\s)
I don’t know what apostrophe is.

But most of all i just want a single expression. Not 3 individual ones.

Answer 1

You can create your own class with the characters that you need to match, like this:

Pattern.compile("[a-zA-Z\\s']+");
