Thread Priority

[Ragu Sivaraman]

If a Thread's priority is not specified explicitly then in gets a priority of Thread.NORM_PRIORITY
True or
False?

Hello:
As far as i know, it is false.
A Thread inherited the priority from the Thread which created it. u have to use setPriority() method to define the prioirty,otherwise,it can't get the Thread.NORM_PRIORITY which is 5.
If i am wrong ,hope someone can correct me.
Thanks.

Honggui Li is correct. You can test if the Thread has defaultpriority

if( ! Thread.getPriority() == Thread.NORM_PRIORITY  ){
 Thread.setPriority( Thread.NORM_PRIORITY   ) ;
}

Hi Ragu,
A Thread will inherit the priority of the thread that created it unless you specifically set the new threads priority. So the answer would have to be false. A new thread will not always be set to Thread.NORM_PRIORITY.
If the creator thread's priority has not been explicitly set then chances are it's NORM_PRIORITY as that's the priority assigned to <code>main()</code>

public class TestMainPriority {
    public static void main(String[] args){        
        System.out.println( Thread.currentThread().getPriority() );
    }
}
Ouput:  5  // which equals NORM_PRIORITY
