Scala

Can decision-makers realistically steer their development projects from Java to Scala yet, or is it too early? Clearly, such a transition is not without risk. Have the benefits now stacked up to outweigh the risks?

A significant part of the lines of code in any enterprise Java application are devoted to plain old java objects (pojos) that carry data. Although they are simple, they represent a non-trivial effort in development and testing. And they make an application resistant to change because often a small change requires alteration of code in several places. Pojos written in Scala are so simple that the value of mixing Scala into Java development becomes worth the extra startup effort.

Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages. It is also fully interoperable with Java. Code sizes are typically reduced by a factor of two to three when compared to an equivalent Java application.
