overwrite non-abstract methods of the parent class. Can implement its abstract methods.2. Subclasses can implement their own unique methods.3. When the subclass method overrides the parent class method, the parameter part is larger or equal (loose) than the parameter range of the parent class. Explanation: For example > if the parent class's method is ArrayList, then its subclass overrides this method when the parameter is list.4. When a subclass overrides a parent class method, the return valu

The five principles of OO refer to SRP, OCP, LSP, DIP, ISP.Open Closed Principle is the most basic design principle in the Java world, which guides how we build a stable and flexible system.Defined:A software entity such as classes, modules, and functions should be open to extensions and closed for modification.Softeware entities like classes,modules and functions should is open for extension but closed for modifications.The opening and closing princi

2There are two-way associations between classes, but one class does not need the features of another class.Remove unnecessary associations. Motivation: bidirectional Association is useful, but you must pay for it, that is, maintain bidirectional connections and ensure that objects are created and deleted correctly. BesidesProgramMembers are not used to bidirectional Association, which is often the source

In C ++, Concatenation refers to the Association of different parts of a computer program. According to the different stages of association editing, there are two different association methods: static Association editing and Dynamic Association editing. 1. Static Association

In the previous article, we introduced the meaning of Association and the situation in which association is needed. This time we will introduce the automatic association in LoadRunner. Automatic association includes two mechanisms: One is that the LoadRunner prompts the user whether to associate by comparing the s
