TreeMap的实现是红黑树算法的实现,所以要了解TreeMap就必须对红黑树有一定的了解,其实这篇博文的名字叫做:根据红黑树的算法来分析TreeMap的实现,但是为了与Java提高篇系列博文保持一致还是叫做TreeMap比较好。通过这篇博文你可以获得如下知识点: 1、红黑树的基本概念。 2、红黑树增加节点、删除节点的实现过程。 3、红...

The Java ‘TreeMap’ is an implementation of the Map interface based on a Red-Black tree, which is a data structure of type self balancing binary search tree. Unlike ‘HashMap’, ‘TreeMap’ is a ‘SortedMap’, which maintains the order of keys on object insertion. In Java, ‘TreeMap...
像这样形式的函数出现了好多好多,估计项目越大,这样的函数就会越多!而且为了支持多种数据库,他写了三个文件SqlDataProvider.cs、OracleDataProvider.cs、AccessDataProvider.cs,这三个文件里的代码也都差不多。为什么要一边一边的写类似的函数呢?就是因为实体类的属性是不一样的!
