java_多线程_优先级

java多线程示例展示优先级源代码：

 1 package control;
 2 
 3 /**
 4  * 功能:龟兔赛跑
 5  *            线程控制优先级别
 6  * 
 7  *         总结:怎么设置优先级？
 8  *             setPriority 
 9  *             通过设置优先级，数字越大的优先级别越高(1-10)  获取cpu概率大
10  *             默认优先级是5
11  *             final static 
12  *             MIN_PRIORITY  1
13  *             MAX_PRIORITY  10
14  *             通过写到run方法的设置优先级 还有启动线程设置优先级  在run方法中设置的生效

乌龟线程：TortoiseThread.java

 1 package control;
 2 
 3 import java.util.Scanner;
 4 
 5 public class TortoiseThread extends Thread{
 6     private String name;
 7     public TortoiseThread(){
 8     }
 9     public TortoiseThread(String name){
10         super(name);
11     }
12     int count = 0;
13     public void run() {
14         setPriority(10);
15         while(true){
16             count++;
17             Scanner sc = new Scanner(System.in);
18             System.out.println("乌龟领先了====加油。。。"+getName() +" "+getPriority()+" count:"+count);
19         }
20     }
21 }
TortoiseThread.java

兔子线程：RabbitThread.java

 1 package control;
 2 
 3 /**
 4  * 兔子的线程
 5  * @author superdrew
 6  */
 7 public class RabbitRunnable implements Runnable{
 8     int count = 0;
 9     public void run() {
10         Thread.currentThread().setPriority(5);
11         while(true){
12         count++;    
13             System.out.println("兔子领先了-----快加油!"+
14         Thread.currentThread().getName()+" "+Thread.currentThread().getPriority()+" count:"+count);
15         }
16     }    
17 }
RabbitThread.java
