object oriented design and patterns 2nd edition

Recently, I was looking at the JavaScript advanced programming design (the third edition). The object-oriented chapter has more than 20 pages, and I went back and forth for three or five times. The results of each reading were different. The first time I went over it, I was confused, as a result, when I went to bed at

. With this constructor, you can continue to add additional properties and methods to the prototype object. When a custom constructor is created, its prototype object only obtains the constructor property by default, and the other methods inherit from object. When the constructor is called to create a new instance, the internal of the instance will contain a poin

Review the relationship of a constructor, prototype, and instance: each constructor has a prototype object, and the prototype

In this new series of articles, you will learn how to best design and optimize the Enterprise JavaBeans component, how to reduce RMI communication and JNDI access, and how to use Enterprise applications most effectively. In each article, Brett McLaughlin, the main authority in Enterprise Java programming, will provide best practices or design patterns. Many techn

object-oriented, we should first cultivate a way of thinking that focuses on "objects and classes", that is, taking data as the center rather than process as the center. The so-called "shape" refers to some typical object-oriented design techniques used in

a good software design is to try to change If your software is hard to change, the problem may occur when you want to improve the design. Now let's see if several instruments can be easily changed. If a new instrument is added to an existing program, we need to add a new instrument specification and add a new query method to inventory, which does not seem easy to change! It seems that we still ha

Object-oriented design principles are at the heart of oops programming, but most of the Java programmers I've seen are enthusiastic about design patterns like Singleton (singleton), Decorator (adorner), OBSERVER (Observer), Instead of focusing enough attention on learning

GoF（四人帮）那本《设计模式 可复用面向对象软件的基础》可谓是设计模式方面的经典之作，其中介绍的23种设计模式，也可谓是经典中的经典。但是，设计模式的种类绝不仅仅是这23种，除此之外还有很多巧妙可爱的设计模式值得我们学习。这些被遗忘的设计模式，也可以堪称经典之作。今天我们来一起学习被遗忘的设计模式——空对象模式（Null Object Pattern）。一起看看这个模式会带给我们怎样的惊喜？First, Pattern name Provide an object as a surrogate for the lack of an object of a given type.
