1. Design a class that requires a few basic attributes and more than two methods.

(Can be extracted from daily life)

2. Add 2 construction methods for different parameters in a class. 3. Re-design a class that contains the main method to apply the above class and

Test.

4. The job requires programming and debugging through. 5. You should have a detailed description of the class you are designing (what the class encapsulates,

property, the function and meaning of the method, etc.).
