Add a method (call it spotterAnimalArea) to AnimalLab that takes two parameters — animalType and areaID — and returns a String containing the IDs of spotters that have seen the animal in that particular area. You should include only spotters who reported a sighting with count greater than zero. You should exclude duplicate spotter IDs.
Add a method (call it spotterAnimalArea) to AnimalLab that takes two parameters —
animalType and areaID — and returns a String containing the IDs of spotters that have
seen the animal in that particular area. You should include only spotters who reported a
sighting with count greater than zero. You should exclude duplicate spotter IDs.
Hint: Use filters and map to create a stream with all the (possibly duplicate) spotter IDs.
Add these IDs to a set and then use reduce on the corresponding stream to produce the
output. Decide on the correct identity and formulate a two-parameter lambda that
combines the running “sum” with the next element of the stream.
