Java 8 lambda filtering based on condition as well as order

Question

I was trying to filter a list based on multiple conditions, sorting.

class Student{
        private int Age;
        private String className;
        privat         


        

Answer 1

Just to mix and merge the other solutions, you could alternatively do :

Map nameToStudentMap = new HashMap<>();
Set finalListOfStudents = students.stream()
        .map(x -> nameToStudentMap.merge(x.getName(), x, (a, b) -> a.getAge() > b.getAge() ? a : b))
        .collect(Collectors.toSet());
