A modern programming language that makes developers happier.

kotlinlang

I have this Kotlin data class:
```
class Person(override val id: String, val name: String) : HasId 
```
and this Java interface:
```
public interface HasId {
    String getId();
}
```

How do I implement the interface? The above example gives me `'id' overrides nothing`

You must declare the `id` val as private and implement `getId` using a `fun`. You will still be able to use the `object.id` syntax when accessing the field.
