Program to convert Java list of strings to a String in Scala

A java list of strings can be converted to a String in Scala by utilizing toString method of Java in Scala. Here, you 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#

filter_none

edit
close

play_arrow

link
brightness_4
code

// Scala program to convert Java list
// to a String 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 String
        val str = list.toString
          
        // Displays output
        println(str)
      
    }
}

Output:

[geeks, for, geeks]

Here, the duplicate elements are not eliminated and the resultant order of the elements in list is same as stated above.
Example:2#

filter_none

play_arrow

brightness_4
code

// Scala program to convert Java list
// to a String 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("I")
        list.add("am a")
        list.add("writer")
          
        // Converting list to a String
        val str = list.toString
          
        // Displays output
        println(str)
      
    }
}

Output:

[I, am a, writer]

Here, the stated list is not in correct order so, the resultant output is also not in proper order.
