Program to convert Java set of doubles to an Iterable in Scala
A java set of doubles can be converted to an Iterable in Scala by utilizing toIterable method of Java in Scala. Here, you 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 set // to an Iterable in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating set of doubles in Java val set = new java.util.HashSet[Double]() // Adding doubles to the set set.add( 3.56 ) set.add( 9.34 ) set.add( 11.67 ) // Converting set to an Iterable val iterab = set.toIterable // Displays output println(iterab) } } |
Output:
Set(3.56, 9.34, 11.67)
Example:2#
// Scala program to convert Java set // to an Iterable in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating set of doubles in Java val set = new java.util.HashSet[Double]() // Adding doubles to the set set.add( 11.22 ) set.add( 45.22 ) set.add( 69.22 ) // Converting set to an Iterable val iterab = set.toIterable // Displays output println(iterab) } } |
Output:
Set(45.22, 69.22, 11.22)
