regular expression vs patterns matching in Scala
scala> val s = "Me Moscow 2012"
s: String = some text 2012
scala> val PersonLocation = """(.+) (.+) (.+)""".r
PersonLocation: scala.util.matching.Regex = (.+) (.+) (.+)

Created April 4, 2013 13:53
Calling Scala code from Java with java.util.List when Scala's List is expected
// Implicit
import scala.collection.JavaConverters._
// For method:
def doSomething(things: List[Thing]): List[Result] = { ... }
// add the same method with another signature:
def doSomething(things: java.util.List[Thing]): java.util.List[Result] =
doSomething(things.asScala.toList).asJava

class HackUtils {
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
for (int i = 0; i < listAdapter.getCount(); i++) {
