List<Employee> employeeList = new ArrayList<Employee>();
employeeList.add(new Employee(111, "Jiya Brein", 32, "Female", "HR", 2011, 25000.0));
employeeList.add(new Employee(122, "Paul Niksui", 25, "Male", "Sales And Marketing", 2015, 13500.0));
employeeList.add(new Employee(133, "Martin Theron", 29, "Male", "Infrastructure", 2012, 18000.0));
employeeList.add(new Employee(144, "Murali Gowda", 28, "Male", "Product Development", 2014, 32500.0));
employeeList.add(new Employee(155, "Nima Roy", 27, "Female", "HR", 2013, 22700.0));
Optional<Employee> emp = employeeList.stream()
.collect(Collectors.maxBy(Comparator.comparingDouble(Employee::getSalary)));
After sorting the list according to salary in reverse order, you can skip the highest with skip(1) then get the first employee after that with findFirst() method to find the second highest salary.
Try this:
Optional<Employee> emp = employeeList.stream()
.sorted(Comparator.comparingDouble(Employee::getSalary).reversed()).skip(1).findFirst();
System.out.println(emp.get());
Output:
Id : 111, Name : Jiya Brein, age : 32, Gender : Female, Department : HR, Year Of Joining : 2011, Salary : 25000.0
you need to sort the list, then get 2nd (list index starts from 0).
1.
List<Employee> sortedList = employeeList.stream()
.sorted(Comparator.comparingDouble(Employee::getSalary).reversed()).collect(Collectors.toList());
sortedList.get(1)
