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
