What is the result of compiling and running the following program?

[blerimz]

public class ThreadMain {
public static void main(String[] args) {
TestThread th = new TestThread ("TestThread");
th.start(TestThread.MIN_PRIORITY);
}

public void run(){
System.out.println("ThreadMain - run");
}
}

class TestThread extends Thread{
public TestThread(String name){
super(name);
}

public TestThread(Runnable runnable){
super(runnable);
}


public void start(int val){
System.out.println(getName()+" - start");
super.start();
}

public void run(){
System.out.println(getName()+" - run");
TestThread thread = new TestThread(new TestRunnable());
thread.start();
}
}

class TestRunnable implements Runnable{
public void run() {
System.out.println("TestRunnable - run");
}
}

Upon compilation there are two possible outcomes.

1. you get compile errors because the code is wrong
2. it compiles

Upon running there are three possible outcomes.

1. it runs, but throws an exception because there is a bug
2. it runs, doesn't produce an exception but produces the wrong results
3. it runs and works as designed

So yeah, go do it yourself. Compile it and if that works, run it and see what happens. Fingers crossed!

thank you for your reply .

[gimbal2]

Really, that was the answer you wanted? I was basically making a joke.

[blerimz]

well im new in java programming so ...

[gimbal2]

I get that. What I don't get is why you then have code with threading. That's an incredibly advanced topic. Also "a test" ?

[blerimz]

university brother university .

So do u know whats the output of that ?

[masijade]

Well, have you TRIED it yet?

Congratulations! That is your output. All you had to do was compile and run it.

[gimbal2]

University, and then this thread is created :s I just can't believe it.

[blerimz]

its just a thread ......

[gimbal2]

Let's keep it at that. But I hope you get the clue soon.
