Part 1 Start by designing the Employee class Employee holds the following private attributes: a count of employees (a static variable called NUM_EMP)* an employee’s last name an employee’s first name an employeeNumber (a String that is unique – that will use the NUM_EMP)* a department a jobTitle an annual salary (e.g., 45000). NOTE: *NUM_EMP should start off as zero and get updated every time a new Employee is created. The employeeNumber always starts with empl_ followed by the current...

Introduction In this lab, you will be working with three classes: Person, Student, and Roster. Person and Student represent individuals with a first and last name as String class variables, and Student has an additional int class variable that represents a ID number. The Roster class represents a group of people that are objects of either the Person or Student class. It contains an ArrayList. The Person class has been completed for you with class variables, a constructor, and a...
