Given: ...

[Folkert Meeuw]

public class Thread1 
{
public static void main(String[] args)
{
Runnable r = new Runnable()
{
public void run()
{
System.out.print("Cat");
}
};
Threadt=new Thread(r)
{
public void run() 
{
System.out.print("Dog");
}
};
}

}

What is the result ?
(A) Cat
(B) Dog
(C) Compilation fails
(D) The code runs with no output
(E) An exception is thrown at runtime

Compiles fine for me -- eclipse using Java 5.

Hi Guys,

Please, please, please indent your code

You should do it for yourself, so that you'll have an easier time debugging stuff.
You should do it so that when you show your code to other people they won't be tempted to poke your eyes out.

I am not getting error from the command line also.

[Ankur kothari]

cannot find symbol at line 12
symbol: constructor Thread(Runnable)
location: java.lang.Thread
Thread t=new Thread(r);
^

[Ankur kothari]

hey but the code works when i compile it from someother directory

[Ankur kothari]

i have cheecked everything...no thread.class in this directory

[Henry Wong]

Did you happen to create your own Runnable class or interface?

Henry

[Ankur kothari]

(A) Cat

(E) An exception is thrown at runtime

C - If there is mistake on line 12
D - If you fix line 12 and If you do not call t.start();
B - If you fix line 12 and If t.start() is called, because the anonymous class created overrides the run method.
