Java™ How To Program (Early Objects), Tenth Edition

Using the ExecutorService to Manage Threads that Execute PrintTasks

Figure 23.4 uses an ExecutorService object to manage threads that execute PrintTasks (as defined in Fig. 23.3). Lines 11–13 create and name three PrintTasks to execute. Line 18 uses Executors method newCachedThreadPool to obtain an ExecutorService that’s capable of creating new threads as they’re needed by the application. These threads are used by ExecutorService to execute the Runnables.
