Program to apply foreach() method on java list of strings in Scala
  • Last Updated : 29 Nov, 2019

The method foreach() can be applied on Java list of Strings 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, let’s see some examples and then discuss how it works in details.
Example:1#




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

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




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

It is same as above example but here the elements of the list are not present in proper order.
