Java集合详解4:HashMap和HashTable 今天我们来探索一下HashMap和HashTable机制与比较器的源码。 具体代码在我的GitHub中可以找到 https://github.com/h2pl/MyTech 喜欢的话麻烦star一下哈 文章首发于我的个人博客: https://
As of the Java 2 platform v1.2, this class was retrofitted to implement theMapinterface, making it a member of the Java Collections Framework. Unlike the new collection implementations,Hashtableis synchronized. If a thread-safe implementation is not needed, it is recommended to useHashMapin plac...
