What is a typical use of inner classes?

To hide implementation details
As a replacement for inheritance
To use less memory
To make code run faster

The correct answer is: To hide implementation details

Inner classes are primarily used to hide implementation details and provide a more organized structure. Option B is incorrect because inner classes are not meant to replace inheritance but rather to be used in conjunction with them. Option C is incorrect because inner classes do not necessarily use less memory compared to other classes. Option D is incorrect because inner classes do not inherently make code run faster. Overall, option A best describes the typical use of inner classes.
