  • Method Details

    • equals

      public final boolean equals(Object obj)
      Compares two Subset objects for equality. This method returns true if and only if this and the argument refer to the same object; since this method is final, this guarantee holds for all subclasses.
      Overrides:
      equals in class Object
      Parameters:
      obj - the reference object with which to compare.
      Returns:
      true if this object is the same as the obj argument; false otherwise.

    • hashCode

      public final int hashCode()

      Overrides:
      hashCode in class Object
      Returns:
      a hash code value for this object.
