scala> // Simple class example

scala> class SimpleClass {
     | }
defined class SimpleClass

scala> val obj1 = new SimpleClass
obj1: SimpleClass = $iwC$$iwC$SimpleClass@26622cf0

scala> obj1.toString()
res8: String = $iwC$$iwC$SimpleClass@26622cf0

scala>

scala> // Case class example

scala> case class MyCaseClass {
     | }
