java 多線程-優(yōu)先級(jí)

優(yōu)先級(jí)priority，調(diào)用的概率，建議在start之前設(shè)定
.setPriprity(num);可以是數(shù)組或下列常量;
取值1到10,
NORM_PRIORITY 5所有線程默認(rèn)為5
MIN_PRIORITY 1
MAX_PRIORITY 10
.getPriority()獲得當(dāng)前線程優(yōu)先級(jí)

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);

    //設(shè)置優(yōu)先級(jí)在啟動(dòng)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();
}
