A java list of floats can be converted to an Indexed Sequence in Scala by utilizing toIndexedSeq 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#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val list = new java.util.ArrayList[Float]()
list.add( 1.1 f)
list.add( 2.1 f)
list.add( 3.1 f)
val ind = list.toIndexedSeq
println(ind)
}
}
|
Output:
Vector(1.1, 2.1, 3.1)
Example:2#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val list = new java.util.ArrayList[Float]()
list.add( 9.6 f)
list.add( 4.5 f)
list.add( 8.3 f)
val ind = list.toIndexedSeq
println(ind)
}
}
|
Output:
Vector(9.6, 4.5, 8.3)
