Program to convert Java list to Traversable in Scala Last Updated : 03 Dec, 2019 Comments Improve Suggest changes Like Article Like Report A java list can be converted to a Traversable collection in Scala by utilizing toTraversable method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversions work else an error will occur. Now, lets see some examples and then discuss how it works in details. Example:1# Scala // Scala program to convert Java list // to a Traversable in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating list in Java val list = new java.util.ArrayList[Int]() // Adding integers to the list list.add(5) list.add(6) list.add(7) // Converting list to a Traversable val tra = list.toTraversable // Displays Traversable println(tra) } } Output: Buffer(5, 6, 7) Therefore, a Buffer of integer is returned. Here, firstly a list is created where, the int elements are added to it utilizing add method. After that toTraversable method is utilized in order to convert the stated list to a Traversable collection. Example:2# Scala // Scala program to convert Java list // to a Traversable in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating list in Java val list = new java.util.ArrayList[Int]() // Adding integers to the list list.add(3) list.add(1) list.add(2) // Converting list to a Traversable val tra = list.toTraversable // Displays Traversable println(tra) } } Output: Buffer(3, 1, 2) It is same as above example but here the stated list is not in the proper order and the collection returned is also not in proper order.
