Zeek_74_ThreadPriority.java

 

/*

--> Each thread have a priority.

--> Priorities are represented by a number between 1 and 10.

---> In most cases, thread schedular schedules the threads according to their priority

     (known as preemptive scheduling).

 

-->But it is not guaranteed because it depends on JVM specification that which

scheduling it chooses.

3 constants defined in Thread class:

public static int MIN_PRIORITY

public static int NORM_PRIORITY

public static int MAX_PRIORITY

__ Default priority of a thread is 5 (NORM_PRIORITY).

__ The value of MIN_PRIORITY is 1.

__ The value of MAX_PRIORITY is 10.
