      • getInt

        public boolean rem​(int k)
        Description copied from class: AbstractIntCollection
        Removes a single instance of the specified element from this collection, if it is present (optional operation).

        Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

        This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.
