List<EmployeeMax> EmployeeMaxs = new ArrayList<>();

EmployeeMaxs.add(new EmployeeMax("Monu", 32, 77000));

EmployeeMaxs.add(new EmployeeMax("Viru", 28, 30000));

EmployeeMaxs.add(new EmployeeMax("Pri", 20, 35000));

/*

* List<EmployeeMax> sortedList = EmployeeMaxs.stream()

* .sorted(Comparator.comparingInt(EmployeeMax::getSalary)

.reversed()).collect(Collectors.toList());

*/

List<EmployeeMax> sortedList = 

EmployeeMaxs.stream().sorted(Comparator.comparingInt(EmployeeMax::getSalary).reversed()).collect(Collectors.toList());

System.out.println("Seceond Max"+sortedList.get(1));

System.out.println(" Max salary"+sortedList.get(0));

 sortedList.forEach(EmployeeMax -> System.out.println("Employee salary " +
