This article mainly introduces the advantages of Scala, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Scala is a multi-paradigm programming language, similar to Java. The original intention of the design is to implement a scalable language and integrate the features of object-oriented programming and functional programming. You can roughly summarize the following advantages.

1). Java and scala can be seamlessly mixed and run on JVM

2)。 Type inference (automatic type inference) without specifying the type

3)。 Concurrency and distribution (Actor, similar to Java multithreaded Thread)

4)。 Trait trait, characteristic (similar to the combination of interfaces and abstract in java)

5)。 Pattern matching, match case (similar to java switch case)

6)。 High-order function (the parameter of the function is the function, the return of the function is the function), which can be programmed by function.

The bottom layer of spark is written in scala, so it is necessary to understand the scala language in order to make better use of spark, and from java, scala is easy to understand, because there are many grammars and keywords that are the same.
