    • Method Detail

      • 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 - Object the object to compare with this object.
        Returns:
        boolean true if the object is the same as this object false if it is different from this object.

      • hashCode

        public final int hashCode()
        Returns the standard hash code as defined by the Object.hashCode() method. This method is final in order to ensure that the equals and hashCode methods will be consistent in all subclasses.
        Overrides:
        hashCode in class Object
        Returns:
        the receiver's hash.
        See Also:

        Returns:
        String a printable representation for the receiver.
