I am unable to run below code in Scala repl. This is a reproduction from Scala cookbook example provided by Alvin Alexander
This works fine when compiling (scalac) and executing (scala). Can you please tell me how I can make this example work on repl as well? Thanks a lot for your help!
trait Animal {
def speak
}
object Animal {
private class Dog extends Animal {
override def speak = {
println("woof")
}
}
private class Cat extends Animal {
override def speak { println("meow") }
}
def apply(s: String):Animal = {
if (s == "dog") return new Dog
else return new Cat
}
}
# repl
Animal("dog")
# compiling
object test {
def main(args: Array[String]){
Animal(args(0)).speak
}
}
