NavigableMap interface in Java is used to return a key-value mapping associated with the greatest key in this map, or null if the map is empty.
Syntax:
Map.Entry< K, V > lastEntry()
Where, K is the type of key maintained by this map and V is the type of values mapped to the keys.
Parameters: It does not accepts any parameter.
Return Value: It returns a key-value mapping associated with the greatest key in this map, or null if the map is empty.
