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)
      
    }
}


Output:

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)
      
    }
}


Output:

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.
