Software Design Patterns for Java Developers: Expert-led approaches to build re-usable software and enterprise applications – 2nd Edition

article المحتوى

Designing scalable software is difficult; it requires significant effort and knowledge to come up with a design solution that is easy to implement, feasible, adheres to the programming principles, and is scalable in nature. Most functional applications today rely on one or more design patterns to accomplish the complex tasks they were built for.

This book explores the fundamentals of software design and examines a set of widely adopted object-oriented design patterns that have shaped modern software development across industries. In this new edition, you will gain access to expanded technical content featuring dedicated chapters on the bridge pattern for separating abstraction from implementation and the filter pattern for modular data handling. This new edition introduces the composite pattern for tree-like hierarchies and pipeline architectures for sequential task decomposition. You will also find deeper insights into resource bandwidth optimization and refined UML diagrams tailored for mid-to-senior level engineers working on scalable, multi-module systems.

By the end of this book, you will learn to implement the design patterns and understand their purpose, benefits, potential drawbacks, and challenges associated with each of them.
