Interfaces can inherit Interfaces. Abstract classes can implement (implements) interfaces, and abstract classes can inherit concrete Classes. There can be static main methods in an abstract class.Q: Does an abstract class inherit entity classes (concrete Class)A: An abstract class can inherit an entity class, but only if the entity class must have an explicit constructor.The answer is clear and can be Inher

Concrete Mixing tower (Station) management and cost accounting 1) how to manage production? How to confirm the actual concrete mix ratio of the sub-item WBS? 2) how to determine the planned cost of concrete? How is the actual cost calculated? Cost consideration: is it a full cost or only focus on the cost of concrete m

common characteristics, and from other aspects of comparison, they are different.Abstract, is stable, is eternal. The opposite of abstraction is concrete. People tend to say, "You speak too abstract, can you tell me the specific point?"In the development language, there are abstract classes, concrete classes, concrete classes can inherit from the abstract class,

function, but also a number of abstract methods, so that the specific class inheriting it can be based on different characteristics of the abstract method of different abstractions.and the concrete class is the class that we actually apply in the application. For these classes, there can be no abstract method inside, and all methods should have a concrete implementation. At the same time an abstract class
