java---多线程sleep()和setPriority()方法

package ThreadIO2_1.Thread.schedule.v1;

public class MyRunner extends Thread {
private static Object obj = new Object();

public void run() {
synchronized (obj) {
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
System.out.println(this.getName() + "已经被唤醒");
}
for (int i = 1; i < 101; i++) {
System.out.println(Thread.currentThread().getName() + "--No.--"
+ i);
}
}
}

}

package ThreadIO2_1.Thread.schedule.v1;

public class Schedule {
public static void main(String[] args) {
Thread t1 = new MyRunner();
t1.start();
Thread t2 = new MyRunner();
t2.start();
// 采用优先级进行相对调度,相比优先级高的抢占资源的概率要高一些，同样的优先级在前面的调度的更快
t1.setPriority(9);
t2.setPriority(3);
try {
Thread.sleep(2000);
// t2.interrupt();// 强制唤醒t2线程；t2也就是运行中的Thread-1,t1是运行中的Thread-0；
} catch (InterruptedException e) {
System.out.println("~~~");
}

}
}
