Intersection of Two HashSets

In HashSets, different mathematical set operations can be performed, these include union, intersection, and difference. In particular, intersection is a type of set operation where the resultant set will contain elements that are present in both of the sets.

In the above image we can see how it will look like in a Venn diagram, there are different methods to achieve the intersection between HashSets in java.

HashSets is a type of Collection in Java that cannot contain any duplicate values. It is often used when we need to maintain a unique data set in our application, it uses hashing internally to store the elements in it, so operations like searching, insertion, and deletion take only a constant amount of time with HashSets. In this article, we will learn methods to find the Intersection of Two HashSets in Java.
