Java's Visitor pattern is a powerful way to separate an algorithm from an object structure. The Visitor pattern allows you to extend an algorithm or add new functionality to an existing class hierarchy without changing the classes themselves. This is particularly useful in situations where you have a large and complex object structure, and you want to be able to perform different operations on the objects in that structure. By using the Visitor pattern, you can achieve this without having to modify every class in the hierarchy.
