本文全片以问题为导向，阐述Spring的意义
Spring实战Spring的目的简化Java开发问题：很多框架通过强迫应用继承它们的类或实现它们的接口从而导致应用与框架绑死。（侵入式）
Spring构建的应用中，它的类通常没有任何痕迹表明你使用了Spring。最坏的场景是，一个类或许会使用Spring注解，但它依旧是POJO。
1.1.2 依赖注入类相互之间进行协作来完成特定的业务逻辑。就会产生依赖
问题：传统的做法，每个对象负责管理与自己相互协作的对象（即它所依赖的对象）的引用，这将会导...

本指南的读者对象是所有对机器学习有求知欲但却不知道如何开头的朋友。我猜很多人已经读过了“机器学习” ——维基百科词条，倍感挫折，以为没人能给出一个高层次的解释。本文就是你们想要的东西。

假如说我们的终端用户是一位经常坐火车的旅行家，通常他是去车站的售票处购买车 票，然后拿着车票去检票口，再坐上火车，开始一段美好的旅行—-一切似乎都是那么和谐。想象一下，如果他选择的目的地是杭州，而某一趟开往杭州的火车 只剩下最后一张车票，可能在同一时刻，不同售票窗口的另一位乘客也购买了同一张车票。假如说售票系统没有进行...

shuffle()打乱数组的实现在做快排时，为了保证快排nlogn，会打乱数组。然后想着怎么实现，用随机数需要一点技巧。
注意：Collection.shuffle()只能打乱集合，没法打乱数组
思路：在数组长度n内生成一个随机数r，复制arr1的r到arr2上。arr1的最后一个数组替换到r上，n–。重复进行

Java动态代理原理与实现特征：代理类与委托类有同样的接口，代理类主要负责为委托类预处理消息、过滤消息、把消息转发给委托类，以及事后处理消息等。
代理类与委托类之间通常会存在关联关系，一个代理类的对象与一个委托类的对象关联，代理类的对象本身并不真正实现服务，而是通过调用委托类的对象的相关方法，来提供特定的服务。（有点像dubbo？）
简单的说就是，我们在访问实际对象时，是通过代理对象来访问的，代理模式就是在访问实际对象时引入一定程度的间接性，因为这种间接性，可以附加多种用途。

I/O模型与多路复用本文转载自这里，并加上了自身理解，感觉更透彻了
同步、异步、阻塞、非阻塞同步 & 异步同步与异步是针对多个事件(线程/进程)来说的。同步和异步关注的是消息通信机制
如果事件A需要等待事件B的完成才能完成，这种串行执行机制可以说是同步的，这是一种可靠的任务序列，要么都成功，要么都失败。
如果事件B的执行不需要依赖事件A的完成结果，这种并行的执行机制可以说是异步的。事件B不确定事件A是否真正完成，所以是不可靠的任务序列。
