scala.Some cannot be cast to java.lang.String

Solution
Well, it's clear to you from the errors and types that `x.email` is not a `String`...
First, decide how you want to handle `None` (a valid option for something of type `Option[String]`). You then have a number of options, including but not limited to:
x.email match {
case None => ...
case Some(value) => println(value) // value is of type String
}
Alternately, take a look at the `get` and `getOrElse` methods on `class Option`.
If you want to "degrade" the option to a String with a possible `null` value, then use
x.email.orNull // calls getOrElse(null)
Finally, if you just don't care about the `None` case (and want to ignore it), then just use a simple "for comprehension" which will "skip" the body in the `None` case:
for (value <- x.email) {
// value is of type String
}
Problem
In this application, I'm getting this error: ``` scala.Some cannot be cast to java.lang.String ``` When trying this: ``` x.email.asInstanceOf[String] ``` x.email is an Option[String] Edit: I understand that I'm dealing with different types here, I was just wondering if there were a more concise way to do nothing with None then a ``` match { case....} ``` sequence. Because I am casting x.email into a String for JSON purposes, a null field will be handled by the JSON object, and I don't explicitly have to deal with it. Sorry for being unclear!!
