Hey,

There are two ways to find the values which are mention below:

Let's take two new sets

scala> var a=Set(1,4,3,4,2)

a: scala.collection.immutable.Set[Int] = Set(1, 4, 3, 2)

scala> var b=Set(7,9,8,2,8)

b: scala.collection.immutable.Set[Int] = Set(7, 9, 8, 2)
  • Using Set.&() Method

You can call &() on one set, and pass another to it.

scala> a.&(b)

res10: scala.collection.immutable.Set[Int] = Set(2)
  • Using Set.intersect() Method​

scala> a.intersect(b)

res11: scala.collection.immutable.Set[Int] = Set(2)

scala> b.intersect(a)

res12: scala.collection.immutable.Set[Int] = Set(2)

If you want to know more about Apache Spark Scala, It's highly recommended to go for the Apache Spark Certification today.
