If return statement is executed in run function of a thread does the thread stop in java

Question

I was confused that a thread is automatically stops after executing the return statement or it still remains alive. This is code like:

public void run{
 //code goes here
 return;//does the thread stops here;
}

Answer 1

Yes, a Java thread stops when its run method terminates.

Now, this information is, let's say, "common knowledge", because the purpose of the Thread class is to wrap a portion of code and terminate when the code finishes executing.

There is no explicit way to assert this behavior by studying the source code of java.lang.Thread because at some point a native method called start0 is executed.
