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();
}
}
