JAVA进阶6.3——线程的优先级

public class Test{
public static void main(String[] args)
{
Thread xc1=new Thread(new xc1());
Thread xc2=new Thread(new xc2());//线程优先级默认是5
xc1.setPriority(Thread.NORM_PRIORITY+3); //设置线程优先级。数字越大优先级越高
xc1.start();
xc2.start();
}
}

class xc1 implements Runnable{
public void run(){
for(int i=0;i<100;i++){
System.out.println("线程1："+i);
}
}
}
class xc2 implements Runnable{
public void run(){
for (int i=0;i<100;i++){
System.out.println("线程2正在执行"+i);
}
}
}
