A java list of doubles 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 doubles in Java
val list = new java.util.ArrayList[Double]()
// Adding doubles to the list
list.add(4.33)
list.add(34.33)
list.add(2.33)
// Converting list to Stream
val stream = list.toStream
// Displays Stream
println(stream)
}
} |
Output:
Stream(4.33, ?)
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 doubles in Java
val list = new java.util.ArrayList[Double]()
// Adding doubles to the list
list.add(5.67)
list.add(5.03)
list.add(5.92)
// Converting list to Stream
val stream = list.toStream
// Displays Stream
println(stream)
}
} |
Output:
Stream(5.67, ?)
