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.

Introduction to structural design patterns

Structural design patterns focus on how objects and classes are combined to form a system. There are two categories of structural design patterns:

  • Object design patterns: Structural object design patterns are used to describe how to create objects with new functionality
  • Class design patterns: Structural class design patterns utilize inheritance to create interfaces and combine multiple classes to form a larger structure

Examples of both the approaches are provided in this chapter.

The seven structural design patterns presented in this chapter all have an object scope, with the exception of the adapter design pattern. The adapter design pattern has both object and class scope, as illustrated in the following table:

Object scope Class scope
Adapter object pattern Adapter class pattern
Bridge pattern
Composite pattern
