import java.util.Scanner;
//import java.lang.String;
public class Main {
public static int n;
//public static String names;
    //private static String[] nameS;
    //private static String[] nameS;
    /**
     * @param args the command line arguments
     */

    public static void main(String[] args/*,String[] nameS*/) {
        Scanner in=new Scanner(System.in);
        int Da=0;
      int num []=new int[n];
     //int x=0;
     

      System.out.printf("%s\n","Enter the Number of student taking This Couse");
      n=in.nextInt();
       String name[]=new String [n];
      System.out.printf("%s  %s \n", "index","value");
      for (; Da < name.length; Da++ )/*Da 4 Display array*/ {
      System.out.printf( "%5d%8d\n", Da, name[Da] );
    }
      System.out.println("Enter the names of the student");
      String names;
      names=in.nextLine();
        name[n] = new String(names);
