Last Updated :

The method foreach() can be applied on Java set of integers in Scala by utilizing Scala’s JavaConversions object. Moreover, here you need to use JavaConversions object as foreach method is not there in Java language.
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( 7 )
set.add( 8 )
set.add( 9 )
set.foreach(println)
}
}
|
Therefore, every item of the set is printed when foreach method is applied to the stated set of integers.
Example:2#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val set = new java.util.HashSet[Int]()
set.add( 9 )
set.add( 5 )
set.add( 1 )
set.foreach(println)
}
}
|
It is same as above example but here the elements are not stated in proper order but in Set it needs to be in proper order so the resultant output is in proper order.
