Answer
# 1
If this question in core (jave Collection): if you are
using list,it will take the duplicate values. so pass
through this list into set it will remove the duplicate
values.

if this question in J2EE servlets: use post method, it it
is not idempotent. once you add item to cart, it will give
the acknowledge before changing in server.
