How can you access the outer class's reference from an inner class?

Using Outer.this
Directly by the outer class name
It's not possible
Using a special method getOuter()

The correct answer is: Using Outer.this

In Java, when an inner class is accessed from an outer class, it creates a special bond between the two. By using the keyword 'this' in the inner class, the special bond can be accessed in order to obtain the outer class's reference. Options B and C are incorrect as the outer class name cannot be used directly to access its reference and it is indeed possible to access the outer class's reference from an inner class. Option D is incorrect as there is no specific method called getOuter() for accessing the outer class's reference.
