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.

  1. The purposes of creational design patterns are as follows:

    • Separate object creation from the system
    • Support reliance on object creation vice inheritance
    • Encapsulate information regarding which classes are used by a system
    • Protect object creation details
  2. Abstract factory, builder, factory method, prototype, simple factory, and singleton
  3. Object scope and class scope
  4. In Java, abstract classes cannot be instantiated, but they can be inherited
  5. Abstract factory design pattern
  6. Builder design pattern
  7. Factory method design pattern
  8. Prototype design pattern
  9. Simple factory design pattern
  10. Singleton design pattern
