A java set of Strings can be converted to a Vector in Scala by utilizing toVector 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#
// Scala program to convert Java set // to a Vector in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating set of Strings in Java
val set = new java.util.HashSet[String]()
// Adding Strings to the set
set.add( "Geeks" )
set.add( "for" )
set.add( "Geeks" )
// Converting set to a Vector
val vec = set.toVector
// Displays vector
println(vec)
}
} |
Vector(Geeks, for)
Therefore, the resultant output is in same order as stated in the above list and the duplicates are also deleted.
Example:2#
// Scala program to convert Java set // to a Vector in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating set of Strings in Java
val set = new java.util.HashSet[String]()
// Adding Strings to the set
set.add( "My" )
set.add( "name is" )
set.add( "Nidhi" )
// Converting set to a Vector
val vec = set.toVector
// Displays vector
println(vec)
}
} |
Vector(Nidhi, My, name is)
Here, the stated Strings are not stated in proper order but the resultant output is in proper order. As here strings with more number of words are displayed at last and strings of greater length are displayed at first.
