Last Updated :

A java Set can be converted to a Sequence in Scala by utilizing toSeq method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversions work.
Now, lets see some examples and then discuss how it works in details.
Example:1#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val set = new java.util.HashSet[Int]()
set.add( 9 )
set.add( 10 )
set.add( 11 )
val seq = set.toSeq
println(seq)
}
}
|
Output:
ArrayBuffer(9, 10, 11)
Therefore, a Sequence of integers is returned. Here, firstly a set is created where, integer elements are added to it utilizing add method. After that toSeq method is utilized in order to convert the stated set to a Sequence.
Example:2#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val set = new java.util.HashSet[Int]()
set.add( 2 )
set.add( 1 )
set.add( 3 )
val seq = set.toSeq
println(seq)
}
}
|
Output:
ArrayBuffer(1, 2, 3)
It is same as above example but here the elements of the set are not present in a proper order. But the Sequence returned is in proper order.
