Question

I was searching in google for something and I got a code like

public static abstract class LocationResult{
    public abstract void gotLocation(Location location);
}

It’s a nested class but wondering how it could be accessible ?

Answer 1

It must be a nested class: the static keyword on the class (not methods within it) is only used (and syntactically valid) for nested classes. Such static member classes (to use Java in a Nutshell’s common nomenculture) hold no reference to the enclosing class, and thus can only access static fields and methods within it (unlike non-static ones; see any summary of nested classes in Java (also known as inner classes).

It can be accessible like this:

public class EnclosingClass {
  public static abstract class LocationResult{
    public abstract void gotLocation(Location location);
  }
}

EnclosingClass.LocationResult locationResult = ...
