Operations:

1. Get list of all the employees from "California"; Return a List
2. Count the number of Females; Return a Count
3. Add 10 to the ID of each Employee; Return the updated List
4. Sort in the Descending order by employee name (z-a); Return the List
5. Get the details of the second highest employee ID; Return the employee

Solution:

System.out.println(employees.stream().filter(employee->employee.getEmployeeState().equals("California")).collect(Collectors.toList()));
System.out.println(employees.stream().map(emp->emp.getEmployeeID()+10).collect(Collectors.toList()));
System.out.println(employees.stream().filter(employee->employee.getEmployeeGender().equalsIgnoreCase("f")).count());
System.out.println(employees.stream().sorted((e1,e2)->e2.getEmployeeName().compareTo(e1.getEmployeeName())).collect(Collectors.toList()));
Collections.sort(employees, (s1,s2)-> s2.getEmployeeID() - s1.getEmployeeID());
System.out.println(employees.get(1));
