【四】Java多线程之线程优先级

每个线程都有自己的优先级，优先级越高的线程得到CPU的分配的执行时间越多

默认优先级是5，范围从1到10。

public class Priority {
    public static void main(String[] args) {
        Thread t1 = new Thread(new T1());
        Thread t2 = new Thread(new T2());
        t1.setPriority(Thread.NORM_PRIORITY+3);
        t1.start();
        t2.start();
    }
}

class T1 implements Runnable{
    public void run(){
        for(int i =0 ; i<1000;i++){
            System.out.println("T1: " +i);
        }
    }
}

class T2 implements Runnable{
    public void run(){
        for(int i =0 ; i<1000;i++){
            System.out.println("---------------T2: " +i);
        }
    }
}
