请问一下这个题怎么做，一会就要交了，求助收藏
(The Person, Student, Employee, Faculty, and Staff classes) Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses ofEmployee. A person has a name, address, phone number, and email address. A student has a class status (freshman, sophomore, junior, or senior). Define the status as a constant. An employee has an office, salary, and date hired. Define a class named MyDate that contains the fields year, month, and day. A faculty member has office hours and a rank. A staff member has a title. Override the toString method in each class to display the class name and the person’s name.lWrite a test program that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods.l(Optional) Draw the UML diagram for the classes. Implement the classes.有哪位大神请写一下

这个题怎么做的啊？
股票x期望收益率为0.12，贝塔值为1.2，股票y的期望收益率为0.14，贝塔值为1.8，无风险收益率为0.05，市场期望收益率为0.09，则买入股
提问者采纳
按照市场期望收益率为9%来匡算，股票x的收益率应达到5%+1.2*(9%-5%)=9.8%股票y的收益率应达到5%+1.8*(9%-5%)=12.2%股票x的α=12%-9.8%=2.2%，股票y的α=14%-12.2%=1.8%总之，两支股票都有升值的潜力，但是股票x的升值潜力更大一些，更吸引投资者。

用资本资产定价模型求得预期收益率，跟题中的预期收益率是什么关系？
