Hands-On Design Patterns with Java

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 microkernel pattern

The microkernel architectural pattern is also referred to as a plug-in architectural pattern. We typically use this pattern when we create systems with interchangeable components, illustrated in the following diagram as a plug-in:

Microkernel pattern

The general framework of the microkernel architectural pattern is illustrated in the previous diagram. The microkernel contains a system's core logic and functionality. The plug-ins each have a specific functionality and contain application programming interfaces (APIs) for the microkernel to reference.

There are five components involved in the microkernel pattern, as shown in the following list:

  • The microkernel: The microkernel is the core of this architectural pattern. It provides core processing and serves as the middleman between other parts of the architecture. All resources are managed...
