简介 lambda表达式,又称闭包(Closure)或称匿名方法(anonymous method).将Lambda表达式引入JAVA中的动机源于一个叫"行为参数"的模式.这种模式能够解决需求变化带来的问题,使代码变得更加灵活.在JAVA8之前,参数模式十分啰嗦.Lambda表达式通过精简的方式使用行为模式克服了这个缺点 解决什么问题 传递行为.它允许我们将函数当成参数传递给某个方法,或者把代码本身当作数据处理,变成了一等公民.解决重复的代码片段和代码包裹问题. 内置抽象行为.把常见的…

4.3 Writing a Grammar Grammars are capable of describing most, but not all, of the syntax of programming languages. For instance, the requirement that identifiers be declared before they are used, cannot be described by a context-free grammar. Theref…
