    Java Design Patterns

    Java Design Patterns

    Design patterns implemented in Java

    A comprehensive, community-maintained collection of design pattern implementations in Java, offering well-documented, educational examples to help developers understand and apply common architectural solutions. All designs should be as simple as possible. You should start with KISS, YAGNI, and Do The Simplest Thing That Could Possibly Work principles. Complexity and patterns should only be introduced when they are needed for practical extensibility.

    LeetCode Book

    LeetCode Book

    Comprehensive study guide for coding interviews

    ...It organizes problems by topic—arrays, linked lists, stacks/queues, trees/graphs, dynamic programming, greedy, backtracking, and math—so you can study systematically. Explanations are concise but intentional, highlighting why a pattern fits, how to reason about boundary cases, and the time/space trade-offs. Many entries include template code and “swap-in” variations, helping you recognize how the same technique adapts across similar problems. The book also emphasizes problem-solving habits like deriving invariants, choosing appropriate data structures, and verifying with small counterexamples. ...

    Dagger

    Fast dependency injector for Android and Java

    ...Dagger aims to address many of the development and performance issues that have plagued reflection-based solutions. Dagger is a replacement for the FactoryFactory classes that implements the dependency injection design pattern without the burden of writing the boilerplate. It allows you to focus on the interesting classes. Declare dependencies, specify how to satisfy them, and ship your app. Dependency injection frameworks have existed for years with a whole variety of APIs for configuring and injecting. So, why reinvent the wheel? Dagger 2 is the first to implement the full stack with generated code. ...

    Micronaut Data

    Micronaut Data

    Ahead of Time Data Repositories

    ...The problem is worse when combined with Hibernate which maintains its own meta-model as you end up with duplicate meta-models. Micronaut Data instead moves this model into the compiler. Both GORM and Spring Data use regular expressions and pattern matching in combination with runtime generated proxies to translate a method definition on a Java interface into a query at runtime. No such runtime translation exists in Micronaut Data and this work is carried out by the Micronaut compiler at compilation time.

    Framework for Evolutionary Message-Driven Microservices on the JVM

    ...Domain-Driven Design (DDD) defines many concepts and patterns that help design software effectively, in line with the business requirements. Axon separates infrastructural concerns from the domain logic, which, combined with DDD best practices, keeps complexity to a minimum. Event Sourcing is a pattern for data storage, where instead of storing the current state of any entity, all past changes to that state are stored.

    ACHE Focused Crawler

    ACHE is a web crawler for domain-specific search

    ACHE is a focused web crawler. It collects web pages that satisfy some specific criteria, e.g., pages that belong to a given domain or that contain a user-specified pattern. ACHE differs from generic crawlers in sense that it uses page classifiers to distinguish between relevant and irrelevant pages in a given domain. A page classifier can be defined as a simple regular expression (e.g., that matches every page that contains a specific word) or a machine-learning-based classification model. ACHE also automatically learns how to prioritize links in order to efficiently locate relevant content while avoiding the retrieval of irrelevant pages. ...

    Mealer App - insanely good food ordering app

    ...Multiple entities or objects of data representation (User, Client, Chef, Meal, etc.) have to be accessable and modifiable from different parts of the application, and changes in data should be represented on the user interface efficiently. By taking inspiration from the Chain-of-responsibility design pattern, Modal-View-Controller design pattern and the Dispatcher-Action-Handler pattern, we resorted to implementing a code structure and data handling pattern that helps achieve loose coupling, lesser dependency on external frameworks (like Firebase) and more modularization. Every app instance would have UI components (activities), which will only contain code needed for user interface. ...
