Program to convert Java set of characters to a Vector in Scala
A java set of characters 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 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 set = new java.util.HashSet[Char]()
set.add( 'a' )
set.add( 'b' )
set.add( 'c' )
val vec = set.toVector
println(vec)
}
}
|
Therefore, the resultant output is in same order as stated in the above list and the duplicates are also deleted.
Example:2#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val set = new java.util.HashSet[Char]()
set.add( 'c' )
set.add( 'a' )
set.add( 'b' )
val vec = set.toVector
println(vec)
}
}
|
Here, the stated characters are not stated in proper order but the resultant output is in proper order.
