Java连载105-线程的优先级

一、线程的优先级

1.线程优先级的获取的CPU时间片会相对多一点

（1）优先级为1-10

（2）最低为1

（3）最高为10

（4）默认为5

package com.bjpowernode.java_learning;

​

public class D105_1_PriorotyOfMultithread {

  public static void main(String[] arsg) {

   

    System.out.println(Thread.MAX_PRIORITY);

    System.out.println(Thread.MIN_PRIORITY);

    System.out.println(Thread.NORM_PRIORITY);

    System.out.println("=================");

   

    Thread t1 = new Processor105();

    t1.setName("t1");

   

    Thread t2 = new Processor105();

    t2.setName("t2");

   

    System.out.println(t1.getPriority());

    System.out.println(t2.getPriority());

   

    //设置优先级

    t1.setPriority(5);

    t2.setPriority(4);

   

    t1.start();

    t2.start();

  }

}

​

class Processor105 extends Thread{

  public void run() {

    for(int i=0;i<5;i++) {

      System.out.println(Thread.currentThread().getName()+"--->"+i);

    }

  }

}
