#JavaTutorial（Java教程） 在成长的过程中，会学到许多新的知识；在项目实践过程中，经常需要学习新的技术。但经过一段时间后，这些知识点和技术又忘得差不多了，等到要用的时候又要搜索很多的资料从头到尾学习一次，浪费很多的时间，没有沉淀和积累。 在这里，通过文章和代码，把这些知识点和技术的主要内容记录并汇总，供自己快速回顾，也分享给他人。 ## 关键字 * [transient与序列化](src/cn/aofeng/demo/java/lang/TransientDemo.java) ## 数据结构 * [在控制台输出类似目录树的结构](src/cn/aofeng/demo/tree) ## 定时器 * [Timer](src/cn/aofeng/demo/java/util/timer/TimerDemo.java) * [ScheduledExecutorService](src/cn/aofeng/demo/java/util/concurret/ScheduledExecutorServiceDemo.java) ## 数据库 * [Apache DbUtils -
