Special characters in an enum

Question

I want to put the special characters, the parentheses ( \'(\' and \')\' ) and the apostrophe (\'), in an enum.

I had this:

private enum specialChars{

Enum constants must be valid Java identifiers. You can override toString if you would like them displayed differently.

public enum SpecialChars {

    OPEN_PAREN {
        public String toString() {
            return "(";
        }
    },

    CLOSE_PAREN {
        public String toString() {
            return ")";
        }
    },

    QUOTE {
        public String toString() {
            return "'";
        }
    }

}
