threads

[peter_parker]

I have the following code on threads.I have a doubt that is it possible that any of the two threads created ie one and two will execute the 2nd print statement in run method before the first print statement in it?That is print hello first and then the current thread name

public class HelloWorld {
public static void main(String []args){
System.out.println("Hello World");
Runnable r = new Animal();
Thread t =new Thread(r);
Thread t1 =new Thread(r);
t.start();
t.setName("one");
t1.start();
t1.setName("two");
System.out.println(Thread.currentThread().getName( ));
}
}
class Animal implements Runnable{
public void run(){
System.out.println(Thread.currentThread().getName( ));
System.out.println("hello");
}
}

I'm not sure what your question is, but I recommend reading through this tutorial: Lesson: Concurrency (The Java™ Tutorials > Essential Classes)

I am asking that whether it is possible in the above code to have output as :
hello
one
main
hello
two Because print statement for hello occurs after print for thread name.So is it possible for a thread to skip a statement and jump to its next statement and then execute the previous statement as above output??

I'm not sure why you'd want to do this, other than if this is a homework assignment. Either way, the tutorial I linked to you contains explanations for everything you'd need to do.

Keep in mind that threads don't have any magic rules that normal code doesn't. There is no "jumping" around in the code, other than the normal ways. Also, keep in mind that just because you're seeing a certain output most of the time, that doesn't mean it'll work that way every time you run it- you have no synchronization over here, so you can't control (or predict) which order things happen in.
