Program to apply foreach() method on Java Set in Scala
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( "Beginner" ) set.add( "CS portal" ) set.add( "GfG" ) // Applying foreach method on // the set and displaying // output set.foreach(println) } } |
Output:
Beginner 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.
