Program to convert Java Set to List in Scala
A java Set can be converted to a List in Scala by utilizing toList 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[String]()
set.add( "GfG" )
set.add( "is a" )
set.add( "CS-portal" )
val list = set.toList
println(list)
}
}
|
Output:
List(GfG, is a, CS-portal)
Therefore, a list of string is returned. Here, firstly a set is created where, string elements are added to it utilizing add method. After that toList method is utilized in order to convert the stated set to the list of Strings.
Example:2#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val set = new java.util.HashSet[String]()
set.add( "Nidhi" )
set.add( "is an" )
set.add( "Author" )
val list = set.toList
println(list)
}
}
|
Output:
List(nidhi, Author, is an)
It is same as above example but here the string with more words is displayed later than the strings with lesser one.
