Java Comparator Using Lambda Function

Using Object Oriented Programming approach

public class Student {
    private String name;
    private int marks;
    Student(String name, int marks){
        this.name = name;
        this.marks = marks;
    }
    public String getName() {
        return name;
    }

    public int getMarks() {
        return marks;
    }
}

public class Result {
    public static List<Student> getResult(List<Student> personList){
        personList.sort(new Comparator<Student>() {
            @Override
            public int compare(Student s1, Student s2) {
                return s1.getMarks() - s2.getMarks();
            }
        });
        return personList;
    }
}

public class Main {
    public static void main(String[] args) {
        List<Student> studentList = new ArrayList<>();
        studentList.add(new Student("Bob", 32));
        studentList.add(new Student("Carol", 43));
        studentList.add(new Student("Alice", 12));
        studentList.add(new Student("Dave", 57));
        studentList.add(new Student("Eve", 64));
        studentList = Result.getResult(studentList);
        System.out.println("Student list according to result");
        for(Student student: studentList){
            System.out.println("Name: "+student.getName());
        }
    }
}

Using Lambda Expression

public class Student {
    private String name;
    private int marks;
    Student(String name, int marks){
        this.name = name;
        this.marks = marks;
    }
    public String getName() {
        return name;
    }
    public int getMarks() {
        return marks;
    }
}

public class Main {
    public static void main(String[] args) {
        List<Student> studentList = new ArrayList<>();
        studentList.add(new Student("Bob", 32));
        studentList.add(new Student("Carol", 43));
        studentList.add(new Student("Alice", 12));
        studentList.add(new Student("Dave", 57));
        studentList.add(new Student("Eve", 64));
        studentList.sort((Student s1, Student s2) -> s1.getMarks()- s2.getMarks());
        System.out.println("Person list In Sorted Order");
        for (Student student: studentList){
            System.out.println(student.getName());
        }
    }
}
