Functional Extension for Java

ScalaVsJavaslang.md

If you are willing to use Javaslang, Java 8 will look more like Scala.

Scala

val filteredList =
  stringsToFilterList.filter(s => s.nonEmpty && s.startsWith("somePredicate"))

Javaslang

final List<String> filteredList =
  stringsToFilterList.filter(s -> isNotBlank(s) && s.startsWith("somePredicate"));

If you are willing to use Javaslang with Lombok it could look like this ...

   val filteredList =  stringsToFilterList.filter(s -> isNotBlank(s) && s.startsWith("somePredicate"));

(pure Java 8 code)
