很幸运,Java已经帮程序员做好了创建线程同步集合的工作,只消调用集合对应的同步方法就可以了

名称都是以这个形式出现,synchronizedXXX

class="language-class="tags" href="/tags/JAVA.html" title=java>java">import class="tags" href="/tags/JAVA.html" title=java>java.util.*;
public class TestSynchronized 
{
	public static void main(String[] args) 
	{
		//创建四个同步集合
		Collection c = Collections.synchronizedCollection(new ArrayList());
		List class="tags" href="/tags/LIST.html" title=list>list = Collections.synchronizedList(new ArrayList());
		Set s = Collections.synchronizedSet(new HashSet());
		Map m = Collections.synchronizedMap(new HashMap());
	}
}
