Answer / Avneesh Kumar
A thread pool in Java is a collection of worker threads that can be reused to execute tasks concurrently. By using a thread pool, you can manage the number of threads actively executing tasks at any given time, preventing the creation and destruction of too many threads. This helps reduce the overhead associated with creating new threads, improves performance by minimizing context switching, and promotes efficient resource utilization.
