      protected Subset​(String name)

  • 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.

      Object.hashCode(), HashMap

    • 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:
      a hash code value for this object.
      See Also:
      Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

    • toString

      public final String toString()
      Returns the name of this subset.
      Overrides:
      toString in class Object
      Returns:
      a string representation of the object.
