what is best design software

11:35:49 IDA 4. I have read about the interface design in your book. I don't think I understand it. What should be formed when the interface design is complete? A demo or a prototype? 11:34:56 qingrun It is the prototype of the interface

difference between = = and JavaScala's = = follows the comparison rules:First check whether the left side is null, if not, call the left manipulation data of the Equals method. Therefore, the exact comparison depends on the definition of the Equals method that makes the operation. Because of the automatic null check, there is no need to manually check it again.java = = can compare primitive types or refere

process, this will improve the quality of software, reduce costs, shorten the development time, so that the development of the more easily, the more efficient, the better, to form a virtuous circle. The framework is not a ready-to-use application system. is a semi-finished product, need later developers to carry out two development, implementation of specific fu

I. Definition English name: decorator pattern, also known as decorator pattern. The decoration mode dynamically extends the functions of an object without changing the original class file and using inheritance. It creates a packaging object, that is, decoration, to package a real object. Ii. Summary When is the decoration mode practical? When the system needs new functions, it adds new code to the old clas

design andProgramThere is a design idea, so there are not so many technical terms or other things. to read this book, I mainly want to understand its ideas and why it is so designed. What are the benefits of such design. At the

What is the adaptation class for java-7.6 adaptation design patterns? Or the adaptation interface? In this chapter, let's discuss the adaptation issue? To put it bluntly, you can use any object to call a method, and this object only needs to comply with certain protocols. The implementation of this protocol has two methods: inheritance and interface, but interfac

The factors that determine the maintainability of the software are:1) comprehensible 2) testability 3) modifiable 4) Portability 5) reusabilityWhat measures should be taken:1) Improved accessibility: Modular • Detailed design documentation • Structured design • Documentation within the program and good high-level programming language2) Improved testability: Good

single change leads to chained changes in dependency modules, the design is rigid. The more modules that must be modified, the more rigid the design. Most developers encounter this situation: they make a seemingly simple change to the requirement. When he actually makes the change, it is found that the impact of man

addition, the specification of software requirements should include non-functional requirements, which describe the behaviors and operations performed by the system to users. It includes standards, specifications, and contracts that must be followed by the product, details of the external interface, performance requirements, design or implementation constraints and quality attributes. The constraint refers

Changes are inevitable. No matter how much you appreciate your software. It may change tomorrow, and it may be difficult to change. This will be reflected in the customer's demand changes. In this chapter, visit an old friend to improve the existing system, and see how to solve large problems with less changes. Do you still remember the boss of the guitar store? We developed a guitar query system. As the business grows better, he wants to start man

encapsulation and reuse, so that we can look at the problem from the point of view of the problem, not from the perspective of the machine.The reuse of software begins with the library and the class library, both of which are in fact white-box multiplexing.
