  • Method Details

    • remove

      public boolean remove​(int k)
      Description copied from interface: IntSet
      Removes an element from this set.
      Specified by:
      remove in interface IntSet
      See Also:
      Collection.remove(Object)

    • rem

      @Deprecated public boolean rem​(int k)
      Deprecated.
      Description copied from interface: IntCollection
      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().

      Specified by:
      rem in interface IntCollection
      Specified by:
      rem in interface IntSet
