A function is a set of statements that perform a task together. You can put your code in a separate function. How to divide your code between different functions, but logically, partitioning is usually to allow each function to perform a specific task. Scala has functions and methods, and our terminology says that the methods and functions are interchangeable in small differences. The Scala approach is to h

Scala is a strong static language that integrates object-oriented and functional features and can run on JVM. Because it can run on JVM and draw on a large number of Java language features during design, it can interact with Java and call Java-related class libraries, this makes great use of the intellectual investment of programmers who have mastered Java. It also draws on the elang function language and Ruby and other scripting languages to provide

Scala"", "Sans-serif" '> and groovy are both JVM-based languages, which have more concise syntax and rich expression capabilities than Java. Scala and groovy are good choices for developers who want to avoid tedious Java statements without leaving the JVM. But which one can take the lead in the future development process? Which one is the future development direction? These are problems that plague develope

Scala has a lot in common with Java, but it's a lot different. This is primarily a Java developer's perspective, summarizing some of the thinking changes that are faced in the process of using Scala. Here is just a summary of the two languages in the development process of the different, will be updated after some switching in the development process is worth noting. The following is a list of some of t

There is a big data project, you know the problem area (problem domain), you know what infrastructure to use, and maybe even decide which framework to use to process all of this data, but one decision has been delayed: which language should I choose? (or perhaps more specifically, the question is, what language should I force all my developers and data scientists to use?) This question will not be postponed for too long, but will be decided sooner or later.Of course, nothing prevents you from us

The name of the Scala language comes from the "extensible language", and Scala is a language that blends the function objects. It can run on the Java platform, and the Scala program is compiled into the JVM's byte code. Their performance is usually consistent with Java programs. Scala code can invoke Java methods, Acce

Seventh step: Parameterized array with typeYou can instantiate an object or class instance using new in Scala. When you instantiate an object in Scala, you can parameterize it with values and types: parameterize. Parameterization means "set" it when you create an instance. Parameterize an instance with a value by passing the object in parentheses to the constructor of the instance. For example, the followin

In the first article in this series, "thinking by using recursion," the authors do not introduce Scala's syntax first, for two reasons: one is because too much of the grammatical details distract the reader, ignoring the basic concept, the basic idea; and the second is that Scala The syntax is very concise, and programmers with other language programming experience can easily read Scala code. Now we're goin
