      To reverse the order of all elements of Java ArrayList use,
      static void reverse(List list) method of Collections class.
     
      This method reverse the order of elements of specified list.

/*
Output would be
Before Reverse Order, ArrayList Contains : [A, B, C, D, E]
After Reverse Order, ArrayList Contains : [E, D, C, B, A]
