Program to apply foreach() method on Java Set in Scala

  • Last Updated : 25 Nov, 2019

The method foreach() can be applied on Java set in Scala by utilizing Scala’s JavaConversions object. Moreover, here we 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#




// Program to apply foreach() method on 
// Java set in Scala
  
// Importing Scala's JavaConversions object
import scala.collection.JavaConversions._
  
// Creating object
object GfG
  
// Main method
def main(args:Array[String])
{
  
    // Creating set in Java
    val set = new java.util.HashSet[String]()
      
    // Adding strings to the set
    set.add("GfG")
    set.add("is a")
    set.add("CS-portal")
      
    // Applying foreach method on 
    // the set and displaying
    // output
    set.foreach(println)
  
}
}
Output:
GfG
is a
CS-portal

Therefore, every item of the set is printed when foreach method is applied to the stated set.
Example:2#




// Program to apply foreach() method on 
// Java set in Scala
  
// Importing Scala's JavaConversions object
import scala.collection.JavaConversions._
  
// Creating object
object GfG
  
// Main method
def main(args:Array[String])
{
  
    // Creating set in Java
    val set = new java.util.HashSet[String]()
      
    // Adding strings to the set
    set.add("Geeks")
    set.add("CS portal")
    set.add("GfG")
      
    // Applying foreach method on 
    // the set and displaying
    // output
    set.foreach(println)
  
}
}
Output:
Geeks
GfG
CS portal

It is same as above example but here the elements of the set with more number of words are printed at last. So, here the stated order is not maintained.
