一般想到Groovy是JVM上的动态语言,都不知道它还有Static Typeing的功能 import groovy.transform.TypeChecked void someMethod() {} @TypeChecked void test() { // compilation error: // cannot find matching method sommeeMethod() sommeeMethod() def name = "Marion" // compilati…

In this lesson, you will learn how to statically type variables in Python 3.6 Static typing can help you avoid errors when consumers of your variables and functions call them with the incorrect data type. You will learn how to statically type strings…

Groovy小结:java调用Groovy方法并传递参数 @(JAVA总结) 1. 场景描述 在网上查了资料发现,java有三种方式调用groovy脚本.但是真正在实际的服务器环境中,嵌入groovy脚本往往需要满足下面的条件: 可以直接调用groovy脚本中的方法 能传递对象到groovy方法中,不仅仅是字符串 提供脚本缓存机制,不用每次调用脚本的时候,都到磁盘读取 修改groovy后能实时生效 只有满足了上面的这些要求,才能安心的将其嵌入到现有的Java后台服务中. 下面就来具体探讨下具体实…

Go所提供的面向对象功能十分简洁,但却兼具了类型检查和鸭子类型两者的有点,这是何等优秀的设计啊! Duck typing in computer programming is an application of the duck test 鸭子测试 鸭子类型 指示编译器将类的类型检查安排在运行时而不是编译时   type checking can be specified to occur at run time rather than compile time. <代码的未来> https:…

SummaryObject-oriented programming was supposed to unify the perspectives of the programmer and the end user in computer code: a boon both to usability and program comprehension. While objects capture structure well, they fail to capture system actio…

为什么是Scala 虽然在大数据领域Java的使用更普及,Python也有后来居上的势头,但Scala一直有着不可动摇的地位.我们熟悉的Spark,Kafka,Flink都是由Scala完成了其核心代码的开发. 所以掌握Scala不仅可以学习大数据组件的源码,而且会极大的提升大数据开发的效率. 这也是Scala的薪资水平一直遥遥领先的原因. 根据2019年全球编程语言薪资统计,排名前几名的Scala无疑是岗位需求与收入同样优秀的语言.当然收入与地域之间也是有区别的,比如在美国,Scala 的收入…
