CODE:

import java.io.*;
import java.util.Scanner; // Import the Scanner class
class Main {
   public static void main (String[] args) {
       System.out.println("Enter number of students\n");
       Scanner myObj = new Scanner(System.in); //creating scanner object
       int numstud = myObj.nextInt(); //taking number of students from user
       int t1=-1;int i1=0;//initializing t1->top first mark, i1-> index of top first student
       int t2=-1;int i2=0;//initializing t2->top second mark, i2-> index of top second student
       int t3=-1;int i3=0;//initializing t3->top third mark, i3-> index of top third student
       for(int i=0;i<numstud;i++)
       {
       System.out.println("Score of student"+(i+1));
       int mrk = myObj.nextInt();
       if(mrk>t1) // if present student mark greater than top first mark
       {
       t3=t2;i3=i2; //previous second holder becomes present third
       t2=t1;i2=i1; //previos first becomes present second
       t1=mrk;i1=i+1; //i+1 th student is top first
       }else if(mrk>t2) //if present student mark less than first but greater than second
       {
       t3=t2;i3=i2;//previous second holder becomes present third
       t2=mrk;i2=i+1;//i+1 th student is top second
       }else if(mrk>t3) //if present student mark less than first and second but greater than third
       {
       t3=mrk;i3=i+1; //i+1 th student is top third
       }
       }
       System.out.println("1st place is student"+i1+ " with "+t1+" points");
       System.out.println("2nd place is student"+i2+ " with "+t2+" points");
       System.out.println("3rd place is student"+i3+ " with "+t3+" points");
      
   }
}
