Set Mappings

Set Mappings:

A Set is a Java collection with no duplicate elements. In more technical terms, sets include just a null component and no combination of e1 and e2, such as e1.equals(e2). To verify whether any two elements/objects are identical, items added to a set must implement both the equals() and hashCode() methods.

A Set is started using Java.util.HashSet and mapped with a set> element in the mapping table. When there are no duplicate elements in the collection, you may utilise the Set collection in your class.
