{

     public static void main(String[] args)

     {

          int a [] = { 101,9,18,4,30,20};

          for (int i = 0; i<a.length; i++)

         {

             for (int j = 0; j<a.length; j++)

             {

                 if (a[i] < a[j])

                 {

                     int temp = a[i];

                     a[i] = a[j];

                     a[j] = temp;

                 }

             }

         }

          System.out.println("Sorted array is :"+Arrays.toString(a));
