Design patterns in software engineering offer reusable solutions to common problems encountered during software design. In Java, these patterns facilitate cleaner, modular, and maintainable code through strategic implementations. The chapter outlines three primary categories of design patterns: Creational, Structural, and Behavioral, each offering specific mechanisms for object creation, composition, and interaction.
Design patterns are templates for solving common problems.
There are 3 main categories: Creational, Structural, and Behavioral.
Common patterns include Singleton, Factory, Adapter, Observer, and Strategy.
Java’s standard libraries themselves make extensive use of these patterns.
Reusable solutions to common problems in software design that promote best practices.
Patterns related to object creation mechanisms.
Patterns concerned with how classes and objects are composed to form larger structures.
Patterns focused on communication between objects.
Ensures a class has only one instance and provides a global access point to it.
Defines an interface for creating objects but allows subclasses to alter the object type created.
Establishes a one-to-many dependency between objects, so when one object changes state, all dependent objects are notified.
