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.

Understanding the service-oriented pattern

The service-oriented architectural pattern, also referred to as Service-Oriented Architecture (SOA), establishes interoperable services through methodologies and rules. Web services are typically designed with an SOA pattern. These interoperable services consist of organized, deployable services with the following characteristics:

  • Runs independently of other services
  • Handles a specific computational task
  • Has access to other services

The SOA pattern can be used to design a group of organized services to provide a cohesive set of services. There are several benefits to adopting this pattern, some of which are listed here:

  • Since the architecture comprises several services, each service can be modified in isolation of the others
  • Increased system flexibility and adaptability
  • The system is easier to maintain because of its modularity
  • Individual...
