A type-specific Set; provides some additional methods that use polymorphism to avoid (un)boxing.
Additionally, this interface strengthens (again) iterator().

- Method Detail
  - iterator
```
DoubleIterator iterator()
```
    Returns a type-specific iterator on the elements of this set.
    Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Set.
    
    Specified by:
    
    iterator in interface java.util.Collection<java.lang.Double>

    Specified by:
    
    iterator in interface java.util.Set<java.lang.Double>
    
    Returns:
    
    a type-specific iterator on the elements of this set.
    
    See Also:
    
    Iterable.iterator()
  - remove
```
boolean remove(double k)
```
    Removes an element from this set.
    Note that the corresponding method of a type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface.

  - rem
```
@Deprecated
default boolean rem(double k)
```
    Deprecated.
    Please use remove() instead.
    
    Removes an element from this set.
    This method is inherited from the type-specific collection this type-specific set is based on, but it should not used as this interface reinstates remove() as removal method.
