How do you access the inner class from code within the outer class?

Since inner classes are members of the outer class, you can apply any access modifiers like private , protected to your inner class which is not possible in normal classes. Since the nested class is a member of its enclosing outer class, you can use the dot ( . ) notation to access the nested class and its members.

What is the difference between nested class and inner class in Java?

In Java programming, nested and inner classes often go hand in hand. A class that is defined within another class is called a nested class. An inner class, on the other hand, is a non-static type, a particular specimen of a nested class.

Why do we need inner class in Java?

Java inner class or nested class is a class that is declared inside the class or interface. We use inner classes to logically group classes and interfaces in one place to be more readable and maintainable. Additionally, it can access all the members of the outer class, including private data members and methods.
