Program to convert Java Set to Stream in Scala
A java Set can be converted to a Stream in Scala by utilizing toStream method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversions work.
Now, let’s 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 stream = set.toStream
println(stream)
}
}
|
Therefore, a Stream is returned. Here, firstly a set is created where, integer elements are added to it utilizing add method. After that toStream method is utilized in order to convert the stated set to a Stream.
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 stream = set.toStream
println(stream)
}
}
|
It is same as above example but here the elements of the set are not present in a proper order. But the stream returned is in proper order.
