The inner classes, and then not static, can access even if with some limitation to the variables of the outer class.
Tag: inner class
You can’t access to the members of an outer class from an inner class using the keyword “this”.
In fact, the keyword “this” in an inner class is a reference to the inner class itself.
To have a reference to the outer class, you must use the syntax:
[OuterClassName].this
where [OuterClassName] is the name of the outer class.
