Summary
In this chapter, we presented two examples that explored advanced characteristics of executors. In the first example, we continued with the client/server example of Chapter 2, Managing Lots of Threads – Executors. We implemented our own executor extending the ThreadPoolExecutor class to execute the tasks by priority and to measure the executing time of the tasks per user. We also included a new command to allow the cancellation of tasks.
In the second example, we explained how to use the ScheduledThreadPoolExecutor class to execute periodic tasks. We implemented two versions of a news reader. The first one showed how to use the basic functionality of the ScheduledExecutorService, and the second one showed how to override the behavior of the ScheduledExecutorService class to, for example, change the delay time between the two executions of a task.
In the next chapter, you will learn how to execute Executor tasks that return a result. If you extend the Thread class or implement the Runnable...
