public int size()
FunctionMost function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible.
public boolean containsKey(java.lang.Object k)
FunctionNote that for some kind of functions (e.g., hashes) this method will always return true.

This method must check whether the provided key is in the map using containsKey(). Thus,
it probes the map twice. Implementors of subclasses should override it with a more efficient method.
