1. Creating a wrapper class Employee with last name, first name, phone, email.
2. SOQL query on Contact to fetch lastName, firstName, Phone, email.
3. Taking one by one contact and creating employee based on the data in the contact
4. Adding to a set
 

public class Employee {
        public String lastName;
        public String firstName;
        public String phone;
        public String email;
}
        List<Contact> contacts = [select FirstName,LastName,Phone,Email from Contact];
<!-- Here it is showing me the ERROR 
       ERROR: Missing '<EOF>' at 'List'        
-->
        Set<Employee> employees =new Set<Employee>();
        
        for(Contact c:contacts){
            
            Employee e =new Employee();
            e.LastName=c.LastName;
            e.firstName=c.firstName;
            e.Phone=c.Phone;
            e.Email =c.Email;
            employees.add(e);
        }
