ArrayList employeelist; //define a new reference variable to hold the list of employees

Employeelist = employeedirectory.getEmployeeList(); // retrieve the list of employees from the direcoty

For (Employee currentemployee : employeelist){ If (currentemployee getLastName() equals(ln) ) return currentemployee ;If (currentemployee .getLastName().equals(ln) ) return currentemployee ;

} // keep going back while there is no match

Return null; // the program gets to this line if no mtach was found which means return null;
