Java程序演示setPriority()方法的示例 (Java program to demonstrate example of setPriority() method)

/*  We will use Thread class methods so we are importing 
    the package but it is not mandate because 
    it is imported by default
*/

import java.lang.Thread;

class SetThreadPriority extends Thread {
    // Override run() of Thread class
    public void run() {
        System.out.println("Thread Name : " + Thread.currentThread().getName());
        System.out.println("Current thread priority is : " + Thread.currentThread().getPriority());
        // By using setPriority() method is used to change 
        // the priority of this thread
        Thread.currentThread().setPriority(6);
        System.out.println("New thread priority is : " + Thread.currentThread().getPriority());
    }

    public static void main(String[] args) {
        // Creating an object of SetThreadPriority class
        SetThreadPriority st_priority = new SetThreadPriority();

        // We are setting the name of the thread GetThreadPriority
        st_priority.setName("SetThreadPriority");

        // Calling start() method with SetThreadPriority class 
        // object of Thread class
        st_priority.start();
    }
}
