In the first two sections, we learned about Scala's objects and associated objects, both of which are used to mean the static members of Java. There are no static fields and static methods in Scala. A static member destroys the complete object-oriented model that Scala supports. However, it is possible to implement class-level operations on Scala through the asso

First, prefaceThe Scala program uses Unicode's BMP character set (Wiki:bmp character set), which is not currently supported by the Unicode supplement character set. This chapter defines Scala's syntactic analysis from Scala models and XML models. If not specifically mentioned, the default refers to the Scala model and specifies that the characters are ASCII \u000

Scala is a object-oriented, statically-typed and functional programming language for the JVM. The strength of Scala lies in it's powerful syntax which allows to write readable, manageable code which are short and conc Ise–and It comes with great support for common design pattern (i.e. a special keyword for implementing the Singleton des IGN pattern). There is plenty of good tutorials and introductions for l
