Program to convert Java Set of characters to a String in Scala
A java Set of characters can be converted to a String in Scala by utilizing toString method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversions work.
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 str = set.toString
println(str)
}
}
|
Here, the duplicate elements are eliminated and the resultant order of the elements in set is same as stated above.
Example:2#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val set = new java.util.HashSet[Char]()
set.add( 'd' )
set.add( 'b' )
set.add( 'c' )
val str = set.toString
println(str)
}
}
|
Here, the stated set is not in correct order but the resultant output is in proper order.
