Inner Classes vs. Subclasses in Java

Date: 2023-11-06

Java offers both inner classes (classes defined within another class) and subclasses (classes inheriting from a superclass). Inner classes enhance code organization and encapsulation, accessing the outer class's members. Subclasses, using the extends keyword, create an "is-a" relationship, enabling inheritance and code reuse. The choice depends on the application's needs; subclasses structure hierarchies, while inner classes improve organization and can implement callbacks. Inner classes might have slight performance overhead.
