Java GenericVisitorAdapter: Simplifying Visitor Design Pattern

The Visitor Design Pattern is a well-known behavioral design pattern in object-oriented programming. It allows you to add new operations to existing classes without modifying their source code, making your code more extensible and maintainable. However, implementing the pattern in Java can be challenging and verbose. The good news is that the Java community has come up with a solution to this problem: the Java GenericVisitorAdapter.

The Java GenericVisitorAdapter is a small library that simplifies the implementation of the Visitor Design Pattern in Java. It provides a base class that you can extend to create concrete visitors for your classes. The GenericVisitorAdapter takes care of the boilerplate code, so you only need to define the methods that are specific to your application. This saves you time and makes your code more readable and maintainable.
