An introduction to the Fork/Join framework
The executor framework, introduced in Java 5, provides a mechanism to execute concurrent tasks without creating, starting, and finishing threads. This framework uses a pool of threads that executes the tasks you send to the executor reusing them for multiple tasks. This mechanism provides some advantages to programmers and these are as follows:
It's easier to program concurrent applications because you don't have to worry to create threads.
It's easier to control the resources used by the executor and your application. You can create an executor that only uses a predefined number of threads. If you send more tasks, the executor stores them in a queue until a thread is available.
Executors reduce the overhead introduced by thread creation reusing the threads. Internally, it manages a pool of threads that reuses threads to execute multiple tasks.
The divide and conquer algorithm is a very popular design technique. To solve a problem using this technique...
