Program to convert Java list of Strings to Traversable in Scala

A java list of Strings 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#

code

// 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 Strings in Java
val list = new java.util.ArrayList[String]()
  
// Adding Strings to the list
list.add("i")
list.add("am")
list.add("good")
  
// Converting list to a Traversable 
val tra= list.toTraversable
  
// Displays traversable 
println(tra)
  
}
}

Output:

Buffer(i, am, good)

Here, the stated output is in same order as stated in the given list.

val list = new java.util.ArrayList[String]()
  
// Adding Strings to the list
list.add("i")
list.add("am a")
list.add("girl")
  
// Converting list to a Traversable 
val tra= list.toTraversable
  
// Displays traversable 
println(tra)
  
}
}

chevron_right


Output:

Buffer(i, am a, girl)

Here, the strings with lesser number of words are displayed first and strings of greater length are displayed at last.
