Program to apply foreach() method on java list of strings in Scala
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.
