HOW two Add Duplicate Values in SET

Question

is It possible to add or not? if yes then How??

Answer 1

unsure about which language you are questioning....
but java for instance have the HashSet object which allows to create a list of values WITH NO repetition of values (that is a key property of a set)
ArrayList however can have all the repetitions you'd want

Answer 2
