Preface Scala is a language designed to implement scaleable language. Officially, it is called the hybrid language of object-oriented language and functional language. In addition, Scala can work with JavaProgramSeamless stitching, because Scala files are compiled into. class files and run on JVM. However, what I care more about is itsScaleable ). What is scala
Wen/Haltzman LinksScala mixes object-oriented and functional features. In functional programming languages, functions are "prime citizens" and can be passed and manipulated like any other data type. This feature becomes useful every time you want to pass an algorithm into a detail action. In a functional programming language, you only need to pass in the detail action package as a parameter in the function.
Because yesterday after work a bit sleepy, did not come and write a blog, today will fill it up! Keep this habit going!More about Scala's higher-order functions1.Scala High-order function code implementation: higher-order functions are applied in our functions2. Higher-order function code details: higher-order functions can make method invocation more convenientprintln ("Welcome to the Scala worksheet")//>
The Java version of the spark Big Data Chinese word Segmentation Statistics program was completed, and after a week of effort, the Scala version of the sparkBig Data Chinese Word segmentation Statistics program also made out, here to share to you want to learn spark friends.The following is the final interface of the program, and the Java version is not very different:The following is the Scala engineering
Reflection of exceptions, expressions, and empty In the previous installment, I introduced the innovative way in which the next generation of Java language was used to eliminate the flashy things and complexities in the Java language. In this installment, I'll show how these languages eliminate some of the flaws in Java: exceptions, statements and expressions, and edges around null. An expression A legacy of the Java language inherited from the C language is the distinction between programmin
Soon after I wrote "I also talked about using Scala language (on) on the. NET platform" on the Lenovo ThinkCentre m4000t desktop in my Ubuntu 9.10 operating system, I went home from work. As a result, I will continue to work on the Windows Vista operating system on the Dell migration 1520. First, start sun virtualbox to open a Ubuntu 9.10 operating system. Scala SDK package has not been installed in the Ubu

PrefaceThis article is mainly about Scala's array, Bufferarray, List, more tutorials Please refer to: Scala tutorial This article summarizes the knowledge pointsIf the length is fixed, use array, if the length may vary, use Arraybuffer to provide the initial value, do not use new, the complex object array does not provide the initial value when you must provide new () to access the element with for (Elem Array 1, fixed-length array definition: Define
functions, you can easily add new node types by inheriting the tree, but on the other hand, adding new operations is a chore because you have to modify all the subclasses of the tree.2. When you use pattern matching yes, the situation just reverses, adding a new node type requires you to modify all of the functions that use pattern matching on the tree, but on the other hand, adding a new operation requires adding a pattern matching function.Let's take a closer look at pattern matching, so we'l
Scala is functional. In addition to being a pure object-oriented language, Scala is also a functional language that is "all-inclusive. The idea of functional language is earlier than that of (electronic) computers. It is based on the lambda calculus operator developed in the 1930 s by Alonzo church. First FunctionProgramming LanguageIt is LISP in the late 1950s S. Other popular functional languages include
= Scala> Addmore (10)Res19:int = 11The function values (objects) that are created at run time according to this function text are called closures:closure. The name originates from the "close" action performed on the function text through the binding of the "capture" free variable . function text without a free variable, such as (X:int) + x + 1, is called the closed term:closedterm, here terminology: terms

Clojure was first FP, but because of the JVM, there was a need to make some compromises, including some OO programming methodsScala first is OO, Java syntax is too redundant, a more mediocre language, Scala first do is to simplify, in a more concise way to write Oo, the main use of ' type inference ' can be inferred, you do not have to write, but if only this, it is better to use PythonSo Scala, like its na
