Program to convert Java list to a Vector in Scala Last Updated : 30 Jun, 2021 Comments Improve Suggest changes Like Article Like Report A java list can be converted to a Vector in Scala by utilizing toVector method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversion 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 Vector 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) // Converting list to a Vector val vec= list.toVector // Displays vector println(vec) } } Output: Vector(5, 6) Therefore, a Vector of integer is returned. Here, firstly a list is created where, the int elements are added to it utilizing add method. After that toVector method is utilized in order to convert the stated list to a Vector. Example:2# Scala // Scala program to convert Java list // to a Vector 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(1) // Converting list to a Vector val vec= list.toVector // Displays vector println(vec) } } Output: Vector(5, 6, 1) It is same as above example but here one more element is added in the stated list which is not in a proper order and then its returned here in the form of Vector.
