What is the advantage of executor framework in Java?

It provides mechanisms for safely starting, closing down, submitting, executing, and blocking on the successful or abrupt termination of tasks (expressed as Runnable or Callable ).

What is executors and why?

public interface Executor. An object that executes submitted Runnable tasks.

What is difference between newFixedThreadPool and newCachedThreadPool?

In terms of resources, the newFixedThreadPool will keep all the threads running until they are explicitly terminated. In the newCachedThreadPool Threads that have not been used for sixty seconds are terminated and removed from the cache. Given this, the resource consumption will depend very much in the situation.
