java95-线程的优先级

public class test30 {
    public static void main(String[] args){
        Thread xc11=new Thread(new Xc41());
        Thread xc12=new Thread(new Xc42());
        xc11.setPriority(Thread.NORM_PRIORITY+3);//数字越大，优先级越高，默认为5
        xc11.start();
        xc12.start();
 
    }
}
class Xc41 extends Thread {
    public void run(){
        for (int i=0;i<20;i++){
            System.out.println("第一个线程在被执行"+i);
        }
    }
}
class Xc42 extends Thread {
    public void run(){
        for (int i=0;i<20;i++){
            System.out.println("i线程"+i);
        }
    }
}
运行结果
