Instructions

In this exercise you will be writing code to retrieve the factory employees. Employees have an ID, a name and a department name, like in the tim-from-marketing exercise. The first field of an employee is always an integer number, but the name and the department name may be empty or null. The class constructor receives a parameter of type List, which is populated in the tests. You will be writing two methods: getEmployeeById(int) and getEmployeeDetailsById(int).

1. Get an employee by ID

Implement the getEmployeeById(int) method so that it returns an Optional object.

If the employee does not exist, returns an empty Optional instance.

2. Return the name and department of a given employee in a certain format

Implement the getEmployeeDetailsById(int) method to return a string containing the id, the name and the department of a given employee:

getEmployeeDetailsById(1) => "1 - Tim - Marketing"
getEmployeeDetailsById(3) => "3 - Steve - Engineering"

If the employee does not exist or is null, it returns No employee found for id: [id].
