Can TreeSet be used efficiently for processing an incoming data stream with subsequent reading?

TreeSet in Java (and Android) is implemented based on a red-black tree and maintains elements in sorted order. It can be useful for processing incoming data streams and subsequent reading if you need to store unique elements and quickly retrieve them in sorted order.

However, with large volumes of data and high-frequency insertions, TreeSet can become a bottleneck due to the logarithmic complexity of insertion and search. If data arrives very quickly and minimizing delays is crucial, more specialized data structures or buffering should be considered.

If the data stream is not too intensive and sorting with uniqueness is important, TreeSet is a suitable and convenient option.

Example of using TreeSet:

TreeSet<Integer> set = new TreeSet<>();
set.add(5);
set.add(1);
set.add(3);

for (Integer num : set) {
    System.out.println(num); // Will output 1, 3, 5
}
