public interface ByteCollection
extends Collection<Byte>, ByteIterable
```
A type-specific Collection; provides some additional methods that use polymorphism to avoid (un)boxing.
Additionally, this class defines strengthens (again) iterator().

Method Summary

Modifier and Type	Method	Description
`boolean`	`add(byte key)`	Ensures that this collection contains the specified element (optional operation).
`default boolean`	`add(Byte key)`	Deprecated. Please use the corresponding type-specific method instead.
`boolean`	`addAll(ByteCollection c)`	Adds all elements of the given type-specific collection to this collection.
`boolean`	`contains(byte key)`	Returns `true` if this collection contains the specified element.
`default boolean`	`contains(Object key)`	Deprecated. Please use the corresponding type-specific method instead.
`boolean`	`containsAll(ByteCollection c)`	Checks whether this collection contains all elements from the given type-specific collection.
`ByteIterator`	`iterator()`	Returns a type-specific iterator on the elements of this collection.
`boolean`	`rem(byte key)`	Removes a single instance of the specified element from this collection, if it is present (optional operation).
`default boolean`	`remove(Object key)`	Deprecated. Please use (and implement) the `rem()` method instead.
`boolean`	`removeAll(ByteCollection c)`	Remove from this collection all elements in the given type-specific collection.
`default boolean`	`removeIf(IntPredicate filter)`	Remove from this collection all elements which satisfy the given predicate.
`default boolean`	`removeIf(Predicate<? super Byte> filter)`	Deprecated. Please use the corresponding type-specific method instead.
`boolean`	`retainAll(ByteCollection c)`	Retains in this collection only elements from the given type-specific collection.
`byte[]`	`toArray(byte[] a)`	Returns an array containing all of the elements in this collection; the runtime type of the returned array is that of the specified array.
`byte[]`	`toByteArray()`	Returns a primitive type array containing the items of this collection.
`byte[]`	`toByteArray(byte[] a)`	Deprecated. Please use `toArray()` instead—this method is redundant and will be removed in the future.

```
ByteIterator iterator()
```
    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:
    
    iterator in interface ByteIterable
    
    Specified by:
    
    iterator in interface Collection<Byte>
    
    Specified by:
    
    iterator in interface Iterable<Byte>
    
    Returns:
    
    a type-specific iterator on the elements of this collection.
    
    See Also:
    
    Iterable.iterator()
  - add
```
boolean add(byte key)
```
    Ensures that this collection contains the specified element (optional operation).
    
    See Also:
    
    Collection.add(Object)
  - contains
```
boolean contains(byte key)
```
    Returns true if this collection contains the specified element.
    
    See Also:
    
    Collection.contains(Object)
  - rem
```
boolean rem(byte key)
```
    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().

    Deprecated.
    Please use (and implement) the rem() method instead.

  - toByteArray
```
byte[] toByteArray()
```
    Returns a primitive type array containing the items of this collection.
    
    Returns:
    
    a primitive type array containing the items of this collection.
    
    See Also:
    
    Collection.toArray()
  - toByteArray
```
@Deprecated
byte[] toByteArray(byte[] a)
```
    Deprecated.
    Please use toArray() instead—this method is redundant and will be removed in the future.
    
    Returns a primitive type array containing the items of this collection.
    Note that, contrarily to Collection.toArray(Object[]), this methods just writes all elements of this collection: no special value will be added after the last one.
    
    Parameters:
    
    a - if this array is big enough, it will be used to store this collection.
    
    Returns:
    
    a primitive type array containing the items of this collection.
    
    See Also:
    
    Collection.toArray(Object[])
  - toArray
```
byte[] toArray(byte[] a)
```
    Returns an array containing all of the elements in this collection; the runtime type of the returned array is that of the specified array.
    Note that, contrarily to Collection.toArray(Object[]), this methods just writes all elements of this collection: no special value will be added after the last one.
    
    Parameters:
    
    a - if this array is big enough, it will be used to store this collection.
    
    Returns:
    
    a primitive type array containing the items of this collection.
    
    See Also:
    
    Collection.toArray(Object[])
  - addAll
```
boolean addAll(ByteCollection c)

    Adds all elements of the given type-specific collection to this collection.
    
    Parameters:
    
    c - a type-specific collection.
    
    Returns:
    
    true if this collection changed as a result of the call.
    
    See Also:
    
    Collection.addAll(Collection)
  - containsAll
```
boolean containsAll(ByteCollection c)
```
    Checks whether this collection contains all elements from the given type-specific collection.
    
    Parameters:
    
    c - a type-specific collection.
    
    Returns:
    
    true if this collection contains all elements of the argument.
    
    See Also:
    
    Collection.containsAll(Collection)
  - removeAll
```
boolean removeAll(ByteCollection c)
```
    Remove from this collection all elements in the given type-specific collection.
    
    Parameters:
    
    c - a type-specific collection.
    
    Returns:
    
    true if this collection changed as a result of the call.

    removeIf in interface Collection<Byte>
  - removeIf
```
default boolean removeIf(IntPredicate filter)
```
    Remove from this collection all elements which satisfy the given predicate.
    
    Parameters:
    
    filter - a predicate which returns true for elements to be removed.
    
    Returns:
    
    true if any elements were removed.
    
    See Also:
    
    Collection.removeIf(java.util.function.Predicate)

```
boolean retainAll(ByteCollection c)
```
    Retains in this collection only elements from the given type-specific collection.
    
    Parameters:
    
    c - a type-specific collection.
