1Z0-809 Question #256: Real Exam Question with Answer & Explanation

Given the definition of the Employee class:

class Employee {
 String dept, name;
 public Employee(String d, String n) {
 dept = d;
 name = n;
 }
 public String toString() {
 return getDept() + ":" + getName();
 }
 public String getDept() { return dept; }
 public String getName() { return name; }
}

And this code fragment:

List<Employee> emps = Arrays.asList(new Employee("sales", "Ada"),
 new Employee("sales", "Bob"),
 new Employee("hr", "Bob"),
 new Employee("hr", "Eva"));
Stream<Employee> s = emps.stream()
 .sorted(Comparator.comparing((Employee e) -> e.getDept())
 .thenComparing((Employee e) -> e.getName()));
List<Employee> eSorted = s.collect(Collectors.toList());
System.out.println(eSorted);

What is the result?
