20145105 "Java Programming" experiment Two summary

Experiment Two Java Object-Oriented programming

First, the contents of the experiment:

1. Initial mastery of unit testing and TDD
2. Understanding and mastering object-oriented three elements: encapsulation, polymorphism, modeling
3. Initial mastery of UML
4. Familiarity with S.O.L.I.D principles
5. Understanding Design Patterns

Second, the experimental steps

(a) Unit testing

1. Three kinds of code: pseudo-code, product code, test code

(1) Pseudo-code

(2) Product Code

(3) test code

(4) Error after test result

(5) Making changes

(6) Test error

1. TDD (Test driven development, testing-driven development)

(1) New project, New test catalog, new test Case class

(2) Adding test cases (@Test)

(3) Create a new Myutil class in src to implement the method in the test case

(4) Testing, failure to pass

(5) Modify the Myutil class

(6) test again, by

(ii) Object-oriented three elements

1. Abstraction: Process abstraction, Data abstraction

(1) Process abstraction example (minor changes made)

1. Encapsulation, inheritance, and polymorphism

(1) Encapsulation of classes in Java, such as the Dog class

(2) test code and results

(3) Creating a class diagram of the dog class in UML

(4) Emulate the dog class to implement Cat class

(5)

Not to be continued!!!
