本文探讨了Copy-On-Write机制在并发编程中的应用，通过对比ArrayList与CopyOnWriteArrayList在高并发场景下的表现，展示了CopyOnWrite容器如何解决读写冲突，特别适用于读多写少的场景。

Copy-On-Write是一种程序设计的优化方法，多线程在不修改对象时可以共享一个对象地址空间，如果某一个线程要求修改对象时，需要首先将原来对象复制一份，在新复制的对象地址空间上修改对象内容，其他线程访问此对象时还是访问之前的旧对象，当新对象修改完成后，再将旧对象的指针指向新对象，这种优化方法适合读多写少的场景，体现了读写分离思想。从JDK1.5起;">使用CopyOnWrite机制实现的并发容器,它们是CopyOnWriteArrayList和CopyOnWriteArraySet。CopyOnWrite容器非常有用，可以在非常多的并发场景中使用到。

读取线程

package com.test.util;

import java.util.Iterator;
import java.util.List;

public class ReadThread implements Runnable {
    private List<Integer> list;

    public ReadThread(List<Integer> list) {
        this.list = list;
    }

    @Override
    public void run() {
        for (Iterator<Integer> it=list.iterator();it.hasNext();) {
            Integer num = it.next();
            System.out.println("Thread ID="+Thread.currentThread().getId()+",num="+num);
        }
    }
}

写线程

package com.test.util;

import java.util.List;

public class AddThread implements Runnable {
    private List<Integer> list;

    public AddThread(List<Integer> list) {
        this.list = list;
    }

    @Override
    public void run() {
    	for(int i=0;i<100;i++)
    		this.list.add(9);
    }
}

测试ArrayList对象

package com.test.util;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.concurrent.CopyOnWriteArrayList;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class TestArrayList {

    private void test() {
        List<Integer> tempList = Arrays.asList(new Integer [] {1,2,3,4,5});
        ArrayList<Integer> copyList = new ArrayList<Integer>(tempList);

        //启动十个线程，同时存取集合队列copyList
        ExecutorService executorService = Executors.newFixedThreadPool(10);
        executorService.execute(new ReadThread(copyList));
        executorService.execute(new AddThread(copyList));
        executorService.execute(new AddThread(copyList));
        executorService.execute(new AddThread(copyList));
        executorService.execute(new ReadThread(copyList));
        executorService.execute(new AddThread(copyList));
        executorService.execute(new ReadThread(copyList));
        executorService.execute(new AddThread(copyList));
    }


    public static void main(String[] args) {
        new TestArrayList().test();
    }
}
