java 多线程-优先级

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();
}
}
