  - add
```
public boolean add(long k)
```
    Description copied from interface: LongCollection
    
    Ensures that this collection contains the specified element (optional operation).
    
    Specified by:
    
    add in interface LongCollection
    
    See Also:
    
    Collection.add(Object)
  - rem
```
public boolean rem(long k)
```
    Description copied from interface: LongCollection
    
    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 LongCollection
    
    See Also:
    
    Collection.remove(Object)
  - size
```
public int size()
```
    Specified by:
    
    size in interface Collection<Long>
  - isEmpty
```

    isEmpty in interface Collection<Long>
  - contains
```
public boolean contains(long o)
```
    Description copied from interface: LongCollection
    
    Returns true if this collection contains the specified element.

    contains in interface LongCollection

  - iterator
```
public LongIterator iterator()
```
    Description copied from interface: LongCollection
    
    Returns a type-specific iterator on the elements of this collection.
    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 Collection.
    
    Specified by:
