HashMap是非synchronized,而Hashtable是synchronized,这意味着Hashtable是线程安全的,多个线程可以共享一个Hashtable;而如果没有正确的同步的话,多个线程是不能共享HashMap的。Java 提供了ConcurrentHashMap,它解决了HashMap的线程不安全的问题和Hashtable效率低的问题。 由于Hashtable是线程安全的也是synchronized,所以在单线...

1.数据结构：保存哈希表容器，保存数据的容器 2.哈希函数实现：需要尽可能的将不同的key映射到不同的槽(bucket)中，首先我们采用一种最为简单的哈希算法实现，将key字符串的所有字符加起来，然后以结果对哈希表的大小取模，这样索引就能落在数组索引的范围之内了 3.操作接口函数：初始化，查找，插入，删除，销毁 ...
Java - HashMaps and Null values?, If you have an entry with null value, then it is not possible to tell whether an entry is present in the map or has a null value associated with it. You can either define a constant for such cases (Example: String NOT_VALID = "#NA" ), or you...
