Pair programming

Zoo Inheritance¶

1. Create a command-line application that loads a zoo registry (a file with animal names and their count)
2. Create a trait Animal that defines def talk, def walk and def numberOfLegs
3. Create concrete classes for animals, e.g. Lion, Duck, Cat, Dog
4. Create a sequence of animals and let them talk, walk, and displays numberOfLegs

trait Animal {}
case class Lion(...) extends Animal {}
// ...

val animals = Seq[Animal](...)

animals.foreach { a => ??? }
