Compulsory / Elective: Compulsory
1. Experimental content
Download and install and use the IDEA, following the completion of the experiment ( https://www.cnblogs.com/rocedu/p/6371315.html ).
- Initial grasp of unit testing and TDD
- Understand and master the object-oriented three elements: (! Own to learn) encapsulation, inheritance, polymorphism
- Preliminary master UML modeling
- On completion of the cloud blue ink (1) - (5) experiments.
2. Experimental procedure and results
Object-Oriented Programming (1)
Object-Oriented Programming (2)
Object-Oriented Programming (4)
Object-Oriented Programming (5)
3. Experimental problems encountered in the process and settlement process
- Question 1: When using TDD testing of complex calculator program, because the calculation error leading to an error
- Problem 1 Solution: This embodies the advantages of the idea, this calculation errors and some simple grammatical errors, idea can automatically help us solve.
- Question 2: In doing the fifth point when you submit a problem, because there is no detailed tutorial on the blog, I also can not figure out.
- Problem 2 Solution: to solve the problem with the help of Zhangjing Hao students.
- Question 3: do not understand the meaning of indexOf
Problems Solution 3: This method returns the subscript c in the character string does not exist in the [-1]
Other (perception, thinking, etc.)
Linux just out of reach idea, the idea for the operation is very familiar, but there is
generatealso automatically modify errors are a very useful feature, the future must try to master this tool.
