      • of

        public static java.util.Set<java.lang.Integer> of​(java.lang.String s)
        Parses a range of integers expressed as a string. The string can contain non-negative integers separated by commas, ranges (represented by a hyphen between two integers), and exclusions (represented by a preceding hyphen). For example, "1,2,3-20,-7,-10-15,12".

        Inclusions and exclusions are performed in the order that they are seen. For example, "1-10,-2-9,3-7,-4-6"

        does contain 3, because it is included by "1-10", excluded by "-2-9" and last included by "3-7". But it does not include 4.
        Parameters:
        s - Range set
