I don't understand how to get started. Can someone please explain? Also, how do I do a UML class diagram and jar file? I am studying java.

Create two subclasses:

• Employee with the following fields: first name, last name, zip, email, employee id, salary, exempt flag, job title, years of service
• Customer with the following fields: first name, last name, zip, email, customer id, company, customer type (retail or corporate)

NOTE: Exempt means exempt from laws related to overtime pay (these are usually employees that are salaried as opposed to hourly)

Create a Person class that is the base class of the first two.

• Make sure "users" cannot directly access your fields.
• Provide at least two constructors per class.
• Be sure to initialize all fields within the constructor.
• Provide getters and setters for each field.
• Fully document your code. Javadoc comments are required above the class and each non-trivial method (i.e., any method that contains behavior that could be unexpected).

Be sure to use camel-case field names and methods based on the names above. The Employee class needs a yearsFullyVested "class variable". Provide the appropriate accessor and mutator.
