What will be the output of the following program?
import java.util.*;
public class StudentRanks {
public static void main(String[] args) {
Set<Student> students = new TreeSet<Student>();
students.add(new Student("sreeram", 5, 'C'));
students.add(new Student("karthik", 1, 'A'));
students.add(new Student("Ram", 1, 'B'));
students.add(new Student("Yeshwanthi", 5, 'D'));
students.add(new Student("bhavya", 2, 'E'));
System.out.println(students);
}
}
class Student implements Comparable<Student> {
String name; int rollNumber; char section;
public Student(String name, int rollNumber, char section) {
this.name = name; this.rollNumber = rollNumber;
this.section = section;
}
public int compareTo(Student o) {
return name.substring(rollNumber).compareToIgnoreCase(o.name.substring(o.rollNumber));
}
public String toString() { return name; }
}
