How do you create an instance of an inner class from outside its outer class?

  1. With a special keyword

  2. Just like any other class

  3. Using the outer class object and .new syntax

  4. It's not possible

The correct answer is: Using the outer class object and .new syntax

Inner classes are defined within outer classes and are only accessible from within the outer class. Therefore, to create an instance of an inner class from outside its outer class, we need to use the syntax of outerClass.innerClass to access and instantiate it. In other words, the outer class object is used to access the inner class and the .new syntax is used to instantiate it. Option A is incorrect as there is no special keyword required. Option D is incorrect as it is indeed possible to create an instance of an inner class from outside its outer class. Option B is incorrect as inner classes cannot be instantiated just like any other class as they are dependent on their outer class.
