The last study in my company was about Scala programming language.
It has some merits for Java programmers to understand it and to use it. Although I can’t explain all about Scala in a limited time, I give a detailed explanation of “Functional programming” and “Traits” which is unfamiliar to Java programmers, and touch on collection operations and Actors the model of concurrency.
