About this course

Nested classes, classes that can be found within another class, allow programmers to rationally organize and group classes that may be closely related. One significant benefit of implementing nested classes in Java is that they provide an extra level of security by giving programmers the power to control the amount of access one class may have to another class and its methods.

Skills you'll gain

  • Implement static nested classes

  • Implement non-static nested classes

  • Shadow variables and methods

  • The progress I have made since starting to use codecademy is immense! I can study for short periods or long periods at my own convenience - mostly late in the evenings.

  • I felt like I learned months in a week. I love how Codecademy uses learning by practice and gives great challenges to help the learner to understand a new concept and subject.
