Program to print Java Set of characters in Scala Last Updated : 29 Nov, 2019 Comments Improve Suggest changes Like Article Like Report A java Set of characters 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 characters 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 characters val set = new java.util.HashSet[Char]() // Adding characters to the Set set.add('a') set.add('b') set.add('c') // Displays output println(set) } // Assigning result method to set of characters val set = res } } Output: [a, b, c] Therefore, a set of characters 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 character elements to the stated set one after another and then prints the results. Example:2# Scala // Scala program to print Java Set // of characters 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 characters val set = new java.util.HashSet[Char]() // Adding characters to the Set set.add('j') set.add('l') set.add('k') // Displays output println(set) } // Assigning result method to set val set = res } } Output: [j, k, l] It is same as above example but here one more element is added in the stated set of characters and as it is a set so, the order of the elements is maintained.
