Program to convert Java Set to an Iterator in Scala Last Updated : 29 Nov, 2019 Comments Improve Suggest changes Like Article Like Report A java Set can be converted to an iterator in Scala by utilizing toIterator method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversions work. Now, lets see some examples and then discuss how it works in details. Example:1# Scala // Scala program to convert Java set // to an iterator 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[Int]() // Adding integers to the set set.add(9) set.add(10) set.add(11) // Converting set to an iterator val iter = set.toIterator // Displays output println(iter) } } Output: non-empty iterator Therefore, a non-empty iterator is returned. Here, firstly a set is created where, integer elements are added to it utilizing add method. After that toIterator method is utilized in order to convert the stated set to an iterator. Example:2# Scala // Scala program to convert Java set // to an iterator 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[Int]() // Converting set to an iterator val iter = set.toIterator // Displays output println(iter) } } Output: empty iterator It is same as above example but here there are no elements in the stated list. So, here an empty iterator is returned.
