Exercise – exploring Java executors

Objective: In this exercise, you will explore different types of executors provided by the Java Concurrency API. You will refer to the Java documentation, use a different executor implementation, and observe its behavior in a sample program.

Instructions:

• Visit the Java documentation for the Executors class: https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/Executors.html.
• Read through the documentation and familiarize yourself with the different factory methods provided by the Executors class for creating Executor instances.
• Choose a different executor implementation other than the fixed thread pool used in the previous examples. Some options include the following:
  • Executors.newCachedThreadPool()
  • Executors.newSingleThreadExecutor()
  • Executors.newScheduledThreadPool(int corePoolSize)
• Create a new Java class called ExecutorExploration and replace the Executor creation line with the chosen executor implementation...
