Design Patterns
Hands-On RESTful API Design Patterns and Best Practices: Design, develop, and deploy highly adaptable, scalable, and secure RESTful web APIs
– Every chapter starts from a discussion of a real life software design problem which is then progressively solved by applying one of the patterns.
– Then goes a detailed review of the pattern’s structure and its variations, followed by a code example.
– Then the books shows various applications of the pattern and teaches how to implement the pattern step by step, even in an existing program.
– Each chapter concludes with a discussion of pros and cons of the pattern and its relations, similarities and differences with other patterns.
Java Design Patterns: A Hands-On Experience with Real-World Examples
An ebook on design patterns and the principles behind them
Design patterns help you solve commonly-occurring problems in software design. But you can’t just find a pattern and copy it into your program, the way you can with off-the-shelf functions or libraries. A pattern is not a specific piece of code, but a general concept for solving a particular problem. They are like pre-made blueprints that you can customize to solve a recurring design problem in your code.
The book Dive Into Design Patterns illustrates 22 classic design patterns, and 8 design principles that these patterns are based on.
- Each chapter starts with a real-world software design problem, then solves it using one of the patterns.
- Then we dive into a detailed review of the pattern’s structure and its variations, followed by a code example.
- Then the book shows various applications of the pattern and teaches how to implement the pattern step by step, even in an existing program.
- Each chapter concludes with a discussion of pros and cons of the pattern and explores its relations to, similarities with and differences from other patterns.
Why do you need to know patterns?
Ace interviews and reviews. Questions about patterns come up at almost every programming job interview and every performance review. Get more jobs and get that raise and promotion you so richly deserve.
Extend your programming toolkit. Patterns let you customize ready-made solutions rather than reinvent the wheel. Your code has fewer mistakes because you are using a proven, standard solution covering all hidden problems.
Communicate better with colleagues. Just share the name of the pattern rather than wasting an hour explaining the details of your cool design and its classes to other programmers. Get the glory without the sweat.
Who is this book for?
Pattern Beginners. If you have never studied patterns, the book explains the basic principles of object-oriented programming with real-life examples. Before diving into the patterns, we look at the design values and principles on which the patterns are built.
Pattern Refreshers. If you studied patterns a while ago, but have forgotten things, the ebook can refresh your memory as serve as a handy reference. Quickly find sections of interest without having to read it from start to finish.
Language Switchers. If you are switching to one of the OOP languages (C#, C++, Dart, Go, Java, PHP, Python, Ruby, Rust, Swift, or TypeScript), you will easily grasp the essence of the text thanks to the many real-world examples and analogies, supported by helpful illustrations and diagrams.

The first question you ask yourself is …
What is design patterns?
Design patterns are solutions to general problems that software developers faced during software development. These solutions were obtained by trial and error by numerous software developers over quite a substantial period of time.
The pattern is not a specific piece of code, but a general concept for solving a particular problem, You can follow the pattern details and implement a solution that suits the realities of your own program.
Patterns is not Algorithms!
Patterns are often confused with algorithms, because both concepts describe typical solutions to some known problems.While an algorithm always defines a clear set of actions that can achieve some goal, a pattern is a more high-level description of a solution. The code of the same pattern applied to two different programs may be different.
An analogy to an algorithm is a cooking recipe: both have clear steps to achieve a goal. On the other hand, a pattern is more like a blueprint: you can see what the result and its features are, but the exact order of implementation is up to you.
What does the pattern consist of?
Most of the patterns are described very formally so you can reproduce them in many contacts, design patterns are just pattern for solve problems you can merge two or more design pattern together to solve your own problem.
Why should I learn patterns?
You shouldn’t learn patterns, you can work as a programmer for many years without knowing about single parents a lot of people do just that. Even in that case, though, you might be implementing some patterns without even knowing it, So why would you spend time learning them?
- Design patterns define a common language that you and your teammates can use to communicate more efficiently. You can say, “Oh, just use a Singleton for that,” and everyone will understand the idea behind your suggestion. No need to explain what a singleton is if you know the pattern and its name.
- Design patterns are a toolkit of tried and tested solutions to common problems in software design. Even if you never encounter these problems, knowing patterns is still useful because it teaches you how to solve all sorts of problems using principles of object-oriented design.
Remember this: when you wanna draw circle you’ll use circle pattern, programming is like drawing you use patterns to solve your problem, you can draw circle without a pattern but imagine if your hand tremor that shape will not be circle.
How many design pattern does he have?
We have 23 design patterns named:
- Factory Method
- Abstract Factory
- Builder
- Prototype
- Singleton
- Adapter
- Bridge
- Composite
- Decorator
- Facade
- Flyweight
- Proxy
- Iterator
- Mediator
- Memento
- Observer
- State
- Strategy
- Template Method
- Visitor
- Chain of Responsibility
- Command
- Interpreter
