Hands-On Design Patterns with Java

By: Dr. Edward Lavieri

Overview of this book

Java design patterns are reusable and proven solutions to software design problems. This book covers over 60 battle-tested design patterns used by developers to create functional, reusable, and flexible software. Hands-On Design Patterns with Java starts with an introduction to the Unified Modeling Language (UML), and delves into class and object diagrams with the help of detailed examples. You'll study concepts and approaches to object-oriented programming (OOP) and OOP design patterns to build robust applications. As you advance, you'll explore the categories of GOF design patterns, such as behavioral, creational, and structural, that help you improve code readability and enable large-scale reuse of software. You’ll also discover how to work effectively with microservices and serverless architectures by using cloud design patterns, each of which is thoroughly explained and accompanied by real-world programming solutions. By the end of the book, you’ll be able to speed up your software development process using the right design patterns, and you’ll be comfortable working on scalable and maintainable projects of any size.

Reactive Design Patterns

In the previous chapter, Functional Design Patterns, we examined the functional design pattern category and compared functional design to functional programming. We reviewed and implemented the execute around pattern, lambda pattern, loan pattern, MapReduce pattern, memoization pattern, streams pattern, and tail call pattern.

In this chapter, we will explore the reactive design pattern category and its individual design patterns of asynchronous communication, autoscaling, bounded queue, bulkhead, caching, circuit breaker, event-driven communication, fail fast, failure-handling, fan-out and quickest reply, idempotency, monitoring, publisher-subscriber, self-containment, and stateless. Our exploration of the reactive design patterns is fueled by the desire to design and develop systems that have characteristics of resilient, reliable, scalable, and message...
