The software development process has not changed much over the years. The main problems that need to be faced during the software development process are: the long development cycle makes it difficult to ensure the correctness of the program, difficult to maintain and so on have not been well solved, despite the emergence of object-oriented, framework design and other c

) class, likewise inherited from birds. When you create a Oriole object, the object automatically owns the bird's properties.Through the inheritance system, we can reduce the duplication of information and duplicate statements in the program. If we define two classes separately and do not inherit from the birds, we must enter the birds ' attributes into the definitions of the chickens and the Oriole classes
