Help needed to understand Threads and GC

Question

I have a question about threads
I have a class where my main method is written
public class Main {
    public static void main(String[] args) {
        SomeObject someobject = new SomeObject();
        ThreadClass obj = new ThreadClass();
        obj.set(someobject);
        Thread t1 = new Thread(obj);
        t1.setName("MyThread");
        t1.start();
}Another class
public class SomeObject
    String name = "xyz";
    public void doSomething()
        System.out.println("Done");
}And a runnable class
public class ThreadClass implements Runnable
    SomeObject temp;
    public void set(SomeObject fsTemp)
        temp = fsTemp;
    public void run()
        while(true)
            System.out.println(temp.name);
            temp.doSomething();
            try{Thread.sleep(100);}catch(Exception e){}
}Now when I run this application, once the thread is started "MyThread" the main thread would die, I want to know that if the main thread dies, will the objects created in the main method will be garbage collected??

Answer 1

First of all think yourself: Did you try to run your application? What happened? ?What is the conclusion? Is the Thread object garbage collected?
If you answered the questions above:
Thread objects are kind of special. A reference to the Thread object still exists when the Thread still runs (the run method is executed). This is done because stopping a Thread during its execution is not at all secure. Whenever the run method ends (the Thread is done) the garbage collector will remove the Thread object and all the references needed in there.
