Inner Classes in Java

This course focuses on Inner Classes, which is one of the most fundamental topics in the Java programming language, and yet, one of the more difficult ones. Having an in-depth understanding of this topic is crucial for mastering many advanced topics, such as lambda expressions, and functional interfaces.

Most of the Java courses these days don’t cover the Inner Classes topic in detail, and many simply avoid it. During the years, avoiding this topic wasn’t felt, and most of the Java developers did their work without any special difficulties.

With the emergence of lambda expressions, functional interfaces, and streams in Java 8, and with the continuously growing popularity of using them, the necessity of having an accurate and in-depth understanding of inner classes in Java has become very important.

Learn and Master the Inner Classes topic by Taking this Comprehensive Course.

• Learn about nested classes and about those cases in which the nested class is also an inner class.

• Learn how to define a static nested class and abut the cases in which we can benefit from using it.

• Learn how to define an inner class and about the changes the compiler introduces in our code.

• Learn about the unique connection created between the object we instantiate from the inner class and the object that was already instantiated from the outer class, that in its presence the inner class was instantiated.

• Learn about the limitation that exists when defining an inner class within the scope of a method that was defined in the outer class.

• Learn how to define an anonymous nested class, and learn about using it for passing over a specific functionality from one place in our code to another.

I teach Java programming for nearly 25 years. During these years I developed my unique techniques for explaining complex topics, such as the one this course covers. When developing this course I did my best using small simple code samples together with diagrams I create using my iPad (I use it as a replacement for a blackboard). Even though the explanations are simple when hearing them separately, when putting them all together in one length video it becomes more difficult.

I am dedicated to my students and I am available for any question that arises. In the case that an additional explanation is required I make a special effort and create it.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
