Are you a Java developer looking to elevate your coding skills and architectural knowledge? Look no further than "Open Source Java Design Patterns", the essential guide for mastering the art of design patterns in Java. This comprehensive resource is your gateway to creating robust, maintainable, and scalable software systems.
There are certain universal laws and principles in software development that guide architects, programmers, and anyone needing to design software. This page lists quite a few of those principles, although it's far from complete. This page is a fork of programming-principles repository by Lars Kappert, who has done most of the work collecting the material.

The Abstract Document design pattern in Java is a crucial structural design pattern that provides a consistent way to handle hierarchical and tree-like data structures by defining a common interface for various document types. It separates the core document structure from specific data formats, enabling dynamic updates and simplified maintenance.
The Abstract Factory pattern in Java provides an interface for creating families of related or dependent objects without specifying their concrete classes, enhancing modularity and flexibility in software design.
The Active Object pattern provides a reliable method for asynchronous processing in Java, ensuring responsive applications and efficient thread management. It achieves this by encapsulating tasks within objects that have their own thread and message queue. This separation keeps the main thread responsive and avoids issues like direct thread manipulation or shared state access.
The Acyclic Visitor pattern in Java decouples operations from an object hierarchy, providing a flexible design for various applications.
Real-world example
The Adapter Design Pattern in Java converts the interface of a class into another interface that clients expect, enabling compatibility.
The Ambassador Pattern in Java helps offload common functionalities such as monitoring, logging, and routing from a shared resource to a helper service instance, enhancing performance and maintainability in distributed systems.
