     int num [] = new int [5];

     int a =0;

     int b =0;

     do

     {

         System.out.println(" Enter Your Number......! ");

         num[a] = input.nextInt();

         a++;

     } 

     while (a<5);

     

  System.out.println(" Again Printing these Numbers with do-while Loop");

  do{

      System.out.println(num[b]);

      b++;
