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

The method foreach() can be applied on Java list of characters 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#

filter_none

edit
close

play_arrow

link
brightness_4
code

   
// Program to apply foreach() method on 
// Java list of characters 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 characters in Java
        val list = new java.util.ArrayList[Char]()
          
        // Adding characters to the list
        list.add('e')
        list.add('f')
        list.add('g')
          
        // Applying foreach method on 
        // the list and displaying
        // output
        list.foreach(println)
      
    }
}

Output:

e
f
g

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

filter_none

play_arrow

brightness_4
code

// Program to apply foreach() method on 
// Java list of characters 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 characters in Java
        val list = new java.util.ArrayList[Char]()
          
        // Adding characters to the list
        list.add('j')
        list.add('l')
        list.add('k')
          
        // Applying foreach method on 
        // the list and displaying
        // output
        list.foreach(println)
      
    }
}

Output:

j
l
k

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