函数是一等公民(First-class functions):在函数式编程中,函数可以像普通变量一样进行传递、存储和处理,而且函数可以嵌套定义和返回函数,这些操作可以帮助实现高阶函数和函数组合等编程思想。 纯函数(Pure functions):在函数式编程中,纯函数是指函数没有任何副作用,即不修改函数外部和全局的状态,也不产生任何影响,只依...
Because of the above reasons, we can’t say Java is 100% pure object-oriented. 1.3. What are the tightly encapsulated and loosely encapsulated classes? A tightly encapsulated class does not allow public access to any of its data members and only allows accessors and mutator methods to modify...

Functional programming is a well-known concept in Javascript and python. But, It’s a fancy thing for a java developer. Prior toJava 8, Java has been a pure OOP where objects are first-class citizens. We used to do imperative coding in java. What I meant by imperative here is,we need...
Therefore key features of OOP aren't really useful for developing this kind of applications. 因此,OOP的关键功能对于开发此类应用程序并不是真正有用。 What happens in a typical web app is data flowing: validation, transformation, evaluation and so on. And there's a paradigm that fits perfectly...

在不可空变量调用函数之前,都检查了是否为空, 使用的是kotlin.jvm.internal.Intrinsics这个Java类里面的checkParameterIsNotNull方法。如果是null就抛出异常:public static void checkParameterIsNotNull(Object value, String paramName) { if (value == null) { throwParameterIsNullException(paramName); } }同时,...
