java 多线程-优先级
作者:互联网
优先级priority,调用的概率,建议在start之前设定
.setPriprity(num);可以是数组或下列常量;
取值1到10,
NORM_PRIORITY 5所有线程默认为5
MIN_PRIORITY 1
MAX_PRIORITY 10
.getPriority()获得当前线程优先级
public class n {
public static void main(String[]args) throws InterruptedException
{
System.out.println(Thread.currentThread().getPriority());
test t=new test();
Thread t1=new Thread(t);
Thread t2=new Thread(t);
Thread t3=new Thread(t);
Thread t4=new Thread(t);
Thread t5=new Thread(t);
Thread t6=new Thread(t);
t1.setPriority(Thread.MAX_PRIORITY);
t2.setPriority(Thread.MAX_PRIORITY);
t3.setPriority(Thread.MAX_PRIORITY);
t4.setPriority(Thread.MIN_PRIORITY);
t5.setPriority(Thread.MIN_PRIORITY);
t6.setPriority(Thread.MIN_PRIORITY);
//设置优先级在启动前
t1.start();
t2.start();
t3.start();
t4.start();
t5.start();
t6.start();
}
}
class test implements Runnable
{
public void run()
{
System.out.println(Thread.currentThread().getName()+"-->"+Thread.currentThread().getPriority());
Thread.yield();
}
}
