转--秒杀多线程第四篇 一个经典的多线程同步问题(续)

demo in java:

package com.multithread.main.sampleExample;import com.multithread.main.ExampleInterface;public class SampleExample extends ExampleInterface{    final int MAX_THREAD_NUM = 10;    int g_num = 0;    @Override    public void startDemo() {        int i=0;        while(i<MAX_THREAD_NUM)        {            Thread t = new SampleMultiThread(i);            t.start();            i++;        }    }            class SampleMultiThread extends Thread{        int index = -1;        public SampleMultiThread(int index)        {            this.index = index;                    }                @Override        public void run() {            // TODO Auto-generated method stub            g_num++;            System.out.println("g_num is:"+g_num +"\t"+"index is:"+this.index);        }                            }}

result:

g_num is:2    index is:0
g_num is:8    index is:6
g_num is:7    index is:9
g_num is:6    index is:7
g_num is:5    index is:5
g_num is:4    index is:3
g_num is:3    index is:2
g_num is:2    index is:1
g_num is:10    index is:8
g_num is:10    index is:4
