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> 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?
