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);
         }
     }
 }
