What is a list, set, and map? When should you use each? Correct
Answer-List interface is a ordered collection that allows duplicate and
null values. We can get elements by index.
When there is a need to access elements frequently using the index, or
when you want the elements stored to maintain the insertion order then
use list.
A Set is an unordered collection that won't allow duplicate elements. It
allows null elements, but we can't get elements by key or index .
When the collection should be of unique elements and no duplicates are
tolerated, then go with "Set"
.
Map interface is a unordered collection that allows duplicate elements
but not duplicate keys. It allows null elements but not null keys.
When the data stored should be in the form of key and value then use
map.
