A java list of Shorts can be converted to a Traversable collection in Scala by utilizing toTraversable 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#

   // Scala program to convert Java list  
// to a Traversable 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 Shorts in Java 
        val list = new java.util.ArrayList[Short]() 
          
        // Adding Shorts to the list 
        list.add(-123) 
        list.add(-1000) 
        list.add(-888) 
          
        // Converting list to a Traversable  
        val tra= list.toTraversable 
          
        // Displays traversable  
        println(tra) 
      
    } 
} 
 
  

Output:

  Buffer(-123, -1000, -888)

Example:2#

   // Scala program to convert Java list 
// to a Traversable 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 Shorts in Java 
        val list = new java.util.ArrayList[Short]() 
          
        // Adding Shorts to the list 
        list.add(1000) 
        list.add(123) 
        list.add(898) 
          
        // Converting list to a Traversable  
        val tra= list.toTraversable 
          
        // Displays traversable  
        println(tra) 
      
    } 
} 
 
  

Output:

  Buffer(1000, 123, 898)
