Scala Language Classes and Objects Objects
Example
Whereas Classes are more like blueprints, Objects are static (i.e. already instantiated):
object Dog {
def bark: String = "Raf"
}
Dog.bark() // yields "Raf"
They are often used as a companion to a class, they allow you to write:
class Dog(val name: String) {
}
object Dog {
def apply(name: String): Dog = new Dog(name)
}
val dog = Dog("Barky") // Object
val dog = new Dog("Barky") // Class
