Answer 1

Yes you can! You would need .invoke() method of the method object. Simple example below:

 import scala.util.Try

 case class MyCaseClass(i: String) {
 def sayHi = {
     println(i)
   }
 }
 val hiObj = MyCaseClass("hi")
 val mtdName = "sayHi"
 // Method itself as an object
 val mtd = hiObj.getClass.getMethod(mtdName)
 Try {mtd.invoke(hiObj)}.recover { case _ => ()}
