Finalized()	(Inherited from IJavaPeerable)
ForEach(IBiConsumer)	Performs the given action for each entry in this map until all entries have been processed or the action throws an exception.
Get(Object)	Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.
GetHashCode()	Returns the hash code value for this map.
GetOrDefault(Object, Object)	Returns the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key.
KeySet()	Returns a Set view of the keys contained in this map.
Merge(Object, Object, IBiFunction)	If the specified key is not already associated with a value or is associated with null, associates it with the given non-null value.
