java functional programming example

never want to write code in a language that has no garbage collection. I would rather spend my time on abstraction at a higher level, thinking of ways to solve complex business problems, than wasting time on complex plumbing issues such as memory management. Java eases our interaction with memory management; The functional programming language enables us to rep

As a professional programmer, we often create a library of tools because of our work needs. The so-called tool Library is a function library composed of a set of functions, which is pre-compiled for some common problems that are often encountered at work. Typically, the functionality of these libraries is implemented by a series of functions around these data types, supported by some specially tailored data types. Within the scope of functional

("Increment", 7, (x:int) = x + 1))5println (FormatResult ("Increment2", 7, (x) = x + 1))6println (FormatResult ("Increment3", 7, x = x + 1))7println (FormatResult ("Increment4", 7, _ + 1))8println (FormatResult ("Increment5", 7, X = = {Val r = x + 1; R}))9}The input parameter F of the incoming function formatresult can be a normal function such as factorial,abs. The function text can also be used, as long as its type is int + = Int. The various representations of the above anonymous functions c

Java or C. For example, here we have a point class. The constructor accepts X and Y. There is also a moveBy method that can move a point to some locations. In traditional imperative programming, we will change the status of the Point instance, which may not be a problem during normal times. However, if I submit a point object to three APIs at the same time and t

any side effects is like using final or readonly members in Java or C. For example, here we have a point class. The constructor accepts X and Y.

After more than 50 years of birth, functional programming (functional programming) began to gain more and more attention.Not only did the oldest functional language Lisp regain their youth, but new functional languages such as Erl

programs with the speed of object-oriented programs. Functional programming has been in existence for many years, but there are still a lot of problems to be solved in engineering to use functional programming on a large scale, especially for larger projects. If the understanding of

calculate it!This is the maximum power of lazy evaluation.Of course, the lazy evaluation has such advantages and must have shortcomings, I remember I have seen an example is the most classic:Def Test ():Print (' Please enter a number: ')A = Raw_input ()But if the code is lazy, the first sentence is not necessarily executed before the second sentence.13.
