Hands-On Design Patterns with Java

2 (1)
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.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Next, we have the Mother class, which extends Grandmother and has its own constructor method."

A block of code is set as follows:

    Mother() {
System.out.println("Mother constructor executed.");
}
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

public abstract class MotorHomeAbstractFactory {
public abstract Frame createFrame();
public abstract Style createStyle();
public abstract Engine createEngine();
public abstract Kitchen createKitchen();
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Beneath the Receive Order node is a horizontal black bar referred to as a fork."

Warnings or important notes appear like this.
Tips and tricks appear like this.
