Program to print Java Set of Strings in Scala Last Updated : 29 Nov, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report A java Set of strings can be returned from a Scala program by writing a user defined method of Java in Scala. Here, we don't even need to import any Scala’s JavaConversions object in order to make this conversions work. Now, lets see some examples. Example:1# Scala // Scala program to print Java Set // of strings in Scala // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a java method in Scala def res = { // Creating a java Set of strings val set = new java.util.HashSet[String]() // Adding strings to the Set set.add("Nidhi") set.add("Nisha") // Displays output println(set) } // Assigning result method to set of strings val set = res } } Output: [Nidhi, Nisha] Therefore, a set of strings is returned from a Java method. Here, we don't need to import any object of Scala. In the above program a Java method is written in Scala program. Where, this method adds the string elements of the Set to the stated set one after another and then prints the results. Example:2# Scala // Scala program to print Java Set // of strings in Scala // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a java method in Scala def res = { // Creating a java Set of strings val set = new java.util.HashSet[String]() // Adding strings to the Set set.add("nidhi") set.add("is an") set.add("author") // Displays output println(set) } // Assigning result method to set val set = res } } Output: [nidhi, author, is an] It is same as above example but here one more element is added in the stated set of strings and as it is a set so, the order of the elements is maintained. Hence, the elements with more number of words are printed later than the one with lesser words.
