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 ?

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 = ...
Only nested classes can be static. By doing so you can use the nested class without having an instance of the outer class.
So you could create a class extending it using extends Mainclass.LocationResult and use it with Mainclass.LocationResult instance = ...
