I read the explaination about the priority about the thread.
" the Thread gets the same priority as the thread that has created it."
I am confused about this.
Say, thread A create thread B. A and B have the same priority?
Another question:
class A extends Thread{
}
class B extends Thread{
}
class C{
public static void main(String[] args){
A a= new A();
B b= new B();
}
}
Is there anything talking about the priority about thread A and thread B?
Thanks in advanced
Simon

In this particular case both A and B will inherit the priority of the main system thread that created them, correct me if I'm wrong, which is 5.

VG.

Hi Simon,
This is true.
I Take your example - thread A create thread B.
Now A and B will have the same priority. (refer p284 Khalid).


Another question:
class A extends Thread{
}
class B extends Thread{
}
class C{
public static void main(String[] args){
A a= new A();
B b= new B();
}
}
Is there anything talking about the priority about thread A and thread B?


Here, the threads A and B will get the priority of main thread since it is the parent.
Also, when you don't set the priority of a thread, it assumes a Thread.NORM_PRIORITY.
Hope this helps,

Hi, vadiraj
What means "thread A creates thread B"? Is there typing error? or Do youreally suppose thread A creats Thread B. I think it is our responsible to try our best to give the correct explanation, right?
Your other statements are right. A priority of a thread inherited from its parent, that is, which creats the current thread until the priority is changed explicitly.

Hi George,
Thanks for your reply.
I assumed the fact that in Java every program runs as a thread.
For example, the main thread which is created by JVM.
So in main method(which is indeed a thread) we can create another
thread. That's what I mean by saying Thread A creates Thread B.
Correct me still if I'm wrong.
