containsKey ( Object key ) → bool
Returns true if this map contains the given [key].
containsValue ( Object value ) → bool
Returns true if this map contains the given [value].
forEach ( void action(K key, V value) ) → void
Applies [f] to each key-value pair of the map.
remove ( Object key ) → V
Removes [key] and its associated value, if present, from the map.
toString ( ) → String
Returns a string representation of this object.
