Interpreter pattern is a design pattern that implements a specialized language, allowing the client to express complex operations in a simplified manner. The pattern involves creating an interpreter class that evaluates expressions in the language, and performs the operations specified by the expressions. This pattern can be useful in situations where you want to allow the client to specify complex operations in a concise and easily understandable manner.

J2EE Patterns are a set of design patterns for software development using the Java programming language. These patterns provide solutions to common problems that arise in J2EE-based software development, such as implementing security, managing transactions, and integrating with other systems.

The Service Locator pattern is a J2EE design pattern that abstracts the way to look up and access objects. The objects are managed in a registry, which can be queried for services by client objects.

The Repository Pattern and the Active Record Pattern are different, as the Repository Pattern provides an abstraction over the data access layer, while the Active Record Pattern combines the data access and business logic in a single object.

Adapter pattern is a design pattern that allows objects with incompatible interfaces to work together by converting the interface of one object into an interface expected by the client. This pattern involves creating a wrapper class that implements the target interface and delegates calls to the adaptee object. The adapter acts as a bridge between the adaptee and client, allowing them to work together even if their interfaces are not compatible.

Business Delegate pattern provides a simplified interface to a set of services to reduce the coupling between presentation-tier clients and business services.

The Builder Pattern is used when the construction of an object is complex, and it allows you to build objects step by step, with each step having a different number of options. This is useful when you want to provide a clean API for creating objects, without exposing the details of the creation process. The Factory Pattern, on the other hand, is used when you need to create objects with a single method call. This is useful when the creation process is simple, and you don't need to provide a clean API for creating objects.

Decorator pattern is a design pattern that allows objects to be decorated with additional responsibilities, dynamically, at runtime. The pattern involves creating a decorator class that wraps the original object, adding the new responsibilities to the original object's behavior. This pattern can be useful in situations where you want to add or remove responsibilities from objects dynamically, without affecting the behavior of the original objects.

The Intercepting Filter pattern is a design pattern used in web applications to pre-process requests before they are sent to the target resource. This is done to add additional functionality to the request such as security checks, data validation, or header modification.

The Factory pattern is a creational design pattern that provides a way to create objects in a more efficient and centralized manner. The Factory pattern abstracts the process of object creation and allows the client code to be decoupled from the actual implementation of the objects being created. This allows for greater flexibility and maintainability in the code, as the specific implementation of the objects can be changed without affecting the client code.
