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

Or without streams:

Map map = new HashMap<>();
students.forEach(x -> map.merge(x.getName(), x, (oldV, newV) -> oldV.getAge() > newV.getAge() ? oldV : newV));
Collection max = map.values();
