As I slowly progress in Scala I was trying to get values from a map and if not found return some kind of default value. Being still a java-head, I tried it initially to do it like the following:
var templates:Map[String, String] = Map()
... some code to fill the templates...
// wont compile
def locateTemplate(name: String) : String = {
if (templates.get(name) == null) {
templates.get(name)
}
else {
// by default return the name itself
name
}
}
