Thread pool is ScheduledExecutorService, which I have not used usually. Its biggest advantage is that besides the characteristics of thread pool, it can achieve loop or delay tasks.

The difference between ScheduledExecutorService and Timer

There is only one thread inside the Timer, and if there are multiple tasks, they will be executed sequentially, so there will be problems with our latency and loop time.

ScheduledExecutorService is a thread pool, so this won't happen, and you need to consider using ScheduledExecutorService when you have strict requirements for deferred and recurring tasks.

The usage of ScheduledExecutorService

PublicclassMainActivityextendsAppCompatActivity {

/ / create an instance of ScheduledExecutorService by static method

PrivateScheduledExecutorServicemScheduledExecutorService=Executors.newScheduledThreadPool (4)

@ Override

ProtectedvoidonCreate (BundlesavedInstanceState) {

Super.onCreate (savedInstanceState)

SetContentView (R.layout.activity_main)

/ / delayed task

MScheduledExecutorService.schedule (threadFactory.newThread (newRunnable () {

@ Override

Publicvoidrun () {
