java多线程-线程优先级

优先级顺序

package ThreadTest;
class ThreadRun implements Runnable{

public void run() {
for(int i=0;i<5;i++){
try {
Thread.sleep(1000);
System.out.println(Thread.currentThread().getName()+":"+i);
} catch (InterruptedException e) {
e.printStackTrace();
}

}
}
}
public class ThreadDemo04 {
public static void main(String[] args) {
Thread t1=new Thread(new ThreadRun(),"A");
Thread t2=new Thread(new ThreadRun(),"B");
Thread t3=new Thread(new ThreadRun(),"C");
//设置优先级
t1.setPriority(Thread.MIN_PRIORITY);
t2.setPriority(Thread.NORM_PRIORITY);
t3.setPriority(Thread.MAX_PRIORITY);
t1.start();
t2.start();
t3.start();
}
}
输出结果
C:0
B:0
A:0
C:1
B:1
A:1
B:2
A:2
C:2
C:3
B:3
A:3
C:4
A:4
B:4
最大的线程是T3，对应的是C，可见优先级能提高抢到cpu资源的可能，但不是一定首先抢到c资源
