Parcelable Creator Syntax

AppDeveloper :

Can someone please elaborate on the syntax for Parcelable CREATOR here. for instance it's a static final property, but then I see a class like constructor for a Generic parameter, but no definition of class anywhere, please explain.

public static final Creator<Foo> CREATOR = new Creator<Foo>() {
    @Override
    public Foo createFromParcel(Parcel in) {
        return new Foo(in);
    }

    @Override
    public Foo[] newArray(int size) {
        return new Foo[size];
    }
};

This is the syntax to instantiate an instance of an anonymous class, which implements the Creator interface. This page has more information on anonymous classes
