Question

i create three threads in my main program. i have for loop in each thread. After executing the statements in the run() method , each thread automatically gets destroyed or killed by itself. correct? Is my understanding correct ?

IS there any Java standard reference where it mentions that there is no need to explicitly kill a thread and it does by itself. i have been trying to read and browse many articles. but still not getting 100% confidence.

I would highly appreciate if any expert over here could reply and help me out. Thanks in advance!!!

public class Demo {
    TestA A = new TestA("TestA",threadAList);
    TestA B = new TestB("TestB",threadBList);
    TestA C = new TestC("TestC",threadCList);
}

class TestA implements Runnable {
    Thread t;

    public TestA(String name,List threadAList) {
        System.out.println(name);
        this.threadAList = threadAList;
        t = new Thread(this);
        t.start();
    }

    public void run() {
        try {
            System.out.println("TestA Thread started");
        }
        catch(Exception e) {
            e.printStackTrace(log);
            doing some action to move the faild file to a failure folder    
        }
        finally {
            log.close();
        }
    }
}

Yes, the thread is automatically destroyed and made available for garbage collection once its Runnable‘s run method has returned.
