Program to apply foreach() method on java list of characters in Scala
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#
// 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#
// 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.
