Supposedly Scala requires a completely different programming style. But what happens when you just want a Spring application? Is it possible to program in Scala without jumping in the deep end? Chariot’s John Shepard illustrates the difference in approach in this quick tutorial.
Java 8 is a substantial improvement over Java 7. Here are Java developer John Shepard’s top five favorite features.
