Predict the output :

import java.util.*;
public class student
{
 String s_name;
String s_usn;
void read()
    {
        Scanner sc=new Scanner(System.in);
        System.out.println("enter the student name :");
        s_name=sc.next();
        System.out.println("enter the usn:");
       s_usn=sc.next();
         }
    void print()
    {
        System.out.println(s_name+"\t"+s_usn);
    }
    public static void main(String[] args) {
         student r2[]= new student[10];
     for(int i=0;i20;i++)
        {
        r2[i]=new student();    
        r2[i].read();
        r2[i].print();
        }
        }
}
