Program to convert Java list of characters to Stream in Scala
A java list of characters can be converted to Stream in Scala by utilizing toStream 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 program to convert Java list // to Stream in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating list of characters in Java val list = new java.util.ArrayList[Char]() // Adding characters to the list list.add('a') list.add('b') list.add('c') // Converting list to Stream val stream = list.toStream // Displays Stream println(stream) } } |
Output:
Stream(a, ?)
Example:2#
// Scala program to convert Java list // to Stream in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating list of characters in Java val list = new java.util.ArrayList[Char]() // Adding characters to the list list.add('d') list.add('b') list.add('c') // Converting list to Stream val stream = list.toStream // Displays Stream println(stream) } } |
Output:
Stream(d, ?)
