Given:

public class Emp {

String fName;

String lName;

public Emp (String fn, String ln) {

fName = fn;

lName = ln;

}

public String getfName() { return fName; }

public String getlName() { return lName; }

}

and the code fragment:

List emp = Arrays.asList (

new Emp ("John", "Smith"),

new Emp ("Peter", "Sam"),

new Emp ("Thomas", "Wale"));

emp.stream()

//line n1

.collect(Collectors.toList());

Which code fragment, when inserted at line n1, sorts the employees list in descending order of fName and then ascending order of lName?
