Can we use match to check the type of a class

Question

I\'m new to scala, and I\'m learning the match keyword now.

I wanna know if we can use the keyword match to check the type of a class. My code

Answer 1

This however will compile:

def checkType(cls: AnyRef) {                    
  cls match {                                 
    case s: String => println("is a String")
    case d: Date => println("is a Date")    
    case _ => println("others")             
  }                                                   
}

... or the simplified version of that:

def checkType(cls: AnyRef) =
  cls match {                                 
    case _: String => println("is a String")
    case _: Date => println("is a Date")    
    case _ => println("others")             
  }
