Program to convert Java list of Strings to Stream in Scala
A java list of Strings 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#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val list = new java.util.ArrayList[String]()
list.add( "geeeks" )
list.add( "for" )
list.add( "geeks" )
val stream = list.toStream
println(stream)
}
}
|
Output:
Stream(geeeks, ?)
Example:2#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val list = new java.util.ArrayList[String]()
list.add( "i" )
list.add( "am an" )
list.add( "author" )
val stream = list.toStream
println(stream)
}
}
