Program to convert Java list to a Vector in Scala
A java list can be converted to a Vector in Scala by utilizing toVector method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversion work else an error will occur.
Now, lets see some examples and then discuss how it works in details.
Example:1#
Scala
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val list = new java.util.ArrayList[Int]()
list.add( 5 )
list.add( 6 )
val vec = list.toVector
println(vec)
}
}
|
Therefore, a Vector of integer is returned. Here, firstly a list is created where, the int elements are added to it utilizing add method. After that toVector method is utilized in order to convert the stated list to a Vector.
Example:2#
Scala
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val list = new java.util.ArrayList[Int]()
list.add( 5 )
list.add( 6 )
list.add( 1 )
val vec = list.toVector
println(vec)
}
}
|
It is same as above example but here one more element is added in the stated list which is not in a proper order and then its returned here in the form of Vector.
