函数式编程思想
最近一直在学习函数式编程,函数式编程和面向对象编程都是编程范式的一种。函数式编程解决了一些面向对象解决起来很困难问题,比如并发状态的共享处理,其实函数式不用考虑状态....为了理解什么是函数式编程,我特意买了基本书,也查了一些资料,在这里跟大家分享一下 books 《java8函数式编程》 《函数式编程思想》 《JavaScript函数式编程》

感谢 @lemooljiang 提供的教程,新号终于注册成功,不能发图实在是太不方便了,而且有些时候一图顶千言,能少写大量的文字,最终还是决定用新号来玩了。但这个号还是会继续分享些自己认为不错的技术文章(仅仅是分享原文的连接作为参考) 参考教程 @lemooljiang 传送门>-< 点我

Toilet Bowls and Cisterns on the Street
It’s such a pity when these toilet sets are no longer needed and are discarded like this. I can’t imagine how many times people must have used a toilet set before throwing it away to the skip.

RxJava参考文章
RxJava中backpressure(背压)的概念其实类似与生产者消费模型,backpressure其实解决了生产者生成数据过快带来的问题,细心的人会发现,RxJava2.0中对好多常用的操作符都默认做了backpressure处理,网上的资料也很多,,本人也没这么多时间再次写一遍,所以分享下连接,供将来不时之需,可以省去大量百度,查文档的时间。 虽然有些还是停留在1.0,但是思想是一样的,一通百通。

Kotlin初体验
开发工具: IntelliJIDEA 第一步:打开idea IDE 选中 kotlin 点击next选项 第二步:输入项目的名称及路径后,点击finish按钮 3.创建第一个Kotlin类,名字嘛,随便取吧: 可以发现,Kotlin类的后缀名为*.kt 4.编写第一个程序HelloWorld吧 点击右键运行就会看到输出结果: 如此的简洁,java的所有方法都要依赖于class ,kotlin更符合函数式编程的习惯
