What is the difference between Comparable and Comparator in Java?

Point	Comparable	Comparator
Package	java.lang	java.util
Method	compareTo(T other)	compare(T a, T b)
Where	Inside the class	A separate object or lambda
Orders	One natural order	Many orders

import java.util.ArrayList;
import java.util.Comparator;
import java.util.List;

public class Main {
    record Student(String name, int marks) implements Comparable<Student> {
        @Override
        public int compareTo(Student other) {
            return this.name.compareTo(other.name);      // natural order: by name
        }
    }

    public static void main(String[] args) {
        List<Student> list = new ArrayList<>(List.of(new Student("Meera", 95), new Student("Aman", 72), new Student("Riya", 88)));

        java.util.Collections.sort(list);                        // uses compareTo
        System.out.println(list);

        list.sort(Comparator.comparingInt(Student::marks).reversed());   // another order
        System.out.println(list);
    }
}
