Exercise 1 [40%] Exercise 1A [15%] Create a class called Employee that implements Comparable for type Employee. The Employee class should be able to store role, name and salary of an employee. Role and name should be one word each, the salary a numerical value. The compareTo method should sort first by role, then name, then salary. Additionally override the toString method to print role, name and salary of that employee separated by a single space. Exercise 1B [10%] Create a class called EmployeeInput. This class should have a main() method. In the main method read one line of user input and split it into separate strings using one or more spaces. Use the first value as name, the second as role and the third as salary for creating a new Employee object. Add this employee to an ArrayList containing Employee objects. This should run in a loop until the program is terminated by the user. For example: Please enter name, role and salary of new employee.
