Threads ends when run finish? [duplicate]

Question

I want to know if a thread in java closes itself when run method ends.

I mean, I have a new thread declaration:

new Thread(new SubmitDataOnBackground(handler.getIDValue(), data, this.context)).start();

And then, in SubmitDataOnBackground I have this run method:

public void run() {
    SubmitDataHandler submit = new SubmitDataHandler(ID, data, this.context);
    submit.buildAndSubmitData();

}

After buildandSubmitData finishes, does the thread close itself or I have to add any code somewhere?

I am not sure if I am leaving a new thread opened each time I call this method or it is ok.

My application is a server so it will never ends because it is active the whole time. I just want to know the amount of threads is not outnumbered because it just creates new ones without closing the others when finish.

Answer 1

Threads close themselves after the run method has been called. Read this for further information https://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html

EDIT: If you want to avoid this behaviour, I recommend using ThreadPools.
