RESTful API in Springboot with concurrency support

Notes

• There are two specified APIs to call. One is single threaded. Another uses multi-threaded approach with CompletableFuture.
• GET api that works in a single thread: http://localhost:8080/primes-count?n={input-number}
• GET api that works in multiple (10 at most) threads: http://localhost:8080/primes-count-multithreaded?n={input-number}

Execution Time (single threaded vs multi threaded calculation)

• Single threaded execution time in milliseconds for calculating number of primes from 1~10⁷:
• Multi threaded execution time in milliseconds for calculating number of primes from 1~10⁷:
