Description
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.
