Program to convert Java list of Strings to a Vector in Scala
  • Last Updated : 03 Jan, 2020

A java list of Strings 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#




// Scala program to convert Java list 
// 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 list of Strings in Java
        val list = new java.util.ArrayList[String]()
          
        // Adding Strings to the list
        list.add("Geeks")
        list.add("for")
        list.add("Geeks")
          
        // Converting list to a Vector 
        val vec= list.toVector
          
        // Displays vector
        println(vec)
      
    }
}
Output:
Vector(Geeks, for, Geeks)

Therefore, the resultant output is in same order as stated in the above list and the duplicates are also not deleted.
Example:2#




// Scala program to convert Java list 
// 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 list of Strings in Java
        val list = new java.util.ArrayList[String]()
          
        // Adding Strings to the list
        list.add("My")
        list.add("name is")
        list.add("Nidhi")
          
        // Converting list to a Vector 
        val vec= list.toVector
          
        // Displays vector
        println(vec)
      
    }
}
Output:
Vector(My, name is, Nidhi)

Here, the stated Strings are not stated in proper order so the resultant output is also not in proper order. As here strings with more number of words are displayed first.
