java的线程安全映射

Question

我需要一个线程安全的地图,我有这样的东西:(我对java很新)

 public static class Manager
        {
        static 
        {
//something wrong here, doesn't compile
           list = new java.util.Collections
          .synchronizedMap(new Map<String, Client>());
        }

       static Map<String,Client> list;

        public static void AddClient(Client client)
        {
        // thread safe add client to the list
        }

        public static void RemoveClient(Client client)
        {
        // thread safe remove client to the list
        }

        }

Answer 1

java.util.concurrent.ConcurrentHashMap

Answer 2

包中的ConcurrentHashMap类java.util.concurrent是Map的线程安全实现,它提供了比synchronizedMap(并且具有更高的可伸缩性Hashtable)更好的并发性.请访问http://www.ibm.com/developerworks/java/library/j-jtp07233.html.

Answer 3

使用ConcurrentHashMap
