Hi Guys,
I need a big favour from u. I'm finding difficulty in doing this program.
This is the question- i'm facing difficulty.

Exercise 1:Identify suitable attributes and methods for a company and an employee classes respectivley. Implement both classes in Java.Your methods must reflect at least three collaborative roles for each class. For instance, collaborative roles for a company might include hiring,firing and paying an employee. On the other hand, employee colloborative roles may include working for, managing, or promoting a company.

Exercise 2: Taking into account most employees are obliged to make National Insurance(NI) and Tax contributions, what other class(es) would you consider appropriate to ensure our simple Object-oriented System deals with NI and taxes effectively? (NB: you are not required to implement the classes you consider here, but please justify their selection)
