copied!<p>Functional != function, and for the record I will claim that a method != function...</p> <p>Java is a statically typed, object oriented language. Java has also maintained a relative purity in that manner but it's no where near a functional language.</p> <p>While it's true that you can mimic the behavior of functional programming with imperative programming you're never gonna get that tidy syntax which you'll wanna have for lambda calculus. In a way, if the language doesn't support proper lambda calculus it's not a functional programming language.</p> <p>C++ has functions, but C++ also have classes. C++ therefore have two type of functions, member functions and functions. When you say method you mean a member function. Because the method is invoked on an instance of an object. But when you say static method you mean just function (in the C/C++ sense). This is just a vocabulary for referring to elements of your code. And in Java code can not exist outside a class, a method would imply that it belongs to some class i.e. type.</p> <p>So far nothing of what I've said relates to functional programming but I think you get the point where you wrong.</p> <p>I suggest you look at pure functional programming languages such as Haskell or Erlang. Because functional programming languages generally don't have closers either. </p> <p>Your claim that static methods can be used to mimic functions as first class objects sounds really bizarre to me. It sounds more like a dynamic programming language than functional programming.</p>
