在Thread类中，定义了三个静态值来表示线程的优先级：
MAX_PRIORITY
这是最高的线程优先级，值为10。
NORM_PRIORITY
这是默认的线程优先级，值为5。
MIN_PRIORITY
这是最低的线程优先级，值为1。
语法
public final int getPriority()

Example
public class ThreadPriorityTest extends Thread {
public static void main(String[]args) {
ThreadPriorityTest thread1 = new ThreadPriorityTest();
ThreadPriorityTest thread2 = new ThreadPriorityTest();
ThreadPriorityTest thread3 = new ThreadPriorityTest();
System.out.println("Default thread priority of thread1: " + thread1.getPriority());
System.out.println("Default thread priority of thread2: " + thread2.getPriority());
System.out.println("Default thread priority of thread3: " + thread3.getPriority());
thread1.setPriority(8);
thread2.setPriority(3);
thread3.setPriority(6);
System.out.println("New thread priority of thread1: " + thread1.getPriority());
System.out.println("New thread priority of thread2: " + thread2.getPriority());
System.out.println("New thread priority of thread3: " + thread3.getPriority());
}
