String employee = "please enter the last name of the employee you want to edit";

String edit = "Please enter what you would like to edit";

String employees = JOptionPane.showInputDialog(employee);

String edits = JOptionPane.showInputDialog(edit);

for (int i = 0; i < staffs.size(); i++) {

if (employees.equals(staffs.get(i).getSurname()))

if (edits.equals("first name")) {

String firstName = "Please enter the new first name";

String newFirstName = JOptionPane

.showInputDialog(firstName);

staffs.get(i).setFirstName(newFirstName);

}

else if (edits.equals("surname")) {

String surname = "Please enter the new surname";
