Question

Trying to define an accessor method for default constructor parameter, i.e.:

class Person (age: Int) {
    def age: Int = this.age
}

Which obviously results in a compiler error: ambiguous reference to overloaded definition, both method age in class Person of type => Int and value age in class Person of type Int match expected type Int

Is there a way in this context to distinguish between the member method name and auto-generated member value name?

Of course it’s possible to change the name of either identifier, but is there a way in this scenario of actually specifying which identifier is referred to?

Answer 1

Just put “val” in front of constructor parameters that you want to expose as instance properties.
