Program to convert Java Set to a String in Scala Last Updated : 02 Dec, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report A java Set can be converted to a String in Scala by utilizing toString 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 a String 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 a String val str = set.toString // Displays output println(str) } } Output: [9, 10, 11] Therefore, a String of is returned. Here, firstly a set is created where, integer elements are added to it utilizing add method. After that toString method is utilized in order to convert the stated set to a String. Example:2# Scala // Scala program to convert Java set // to a String 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(3) set.add(1) set.add(2) // Converting set to a String val str = set.toString // Displays output println(str) } } Output: [1, 2, 3] It is same as above example but here the elements of the set are not present in a proper order. But the String returned is in proper order.
