Program to convert Java Set of Strings to Stream in Scala
  • Last Updated : 03 Jan, 2020

A java Set of Strings can be converted to a Stream in Scala by utilizing toStream method of Java in Scala. Here, we 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 set 
// to Stream 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 Stream 
        val stream = set.toStream
          
        // Displays Stream 
        println(stream)
      
    }
}
Output:
Stream(geeks, ?)

Example:2#




// Scala program to convert Java set 
// to Stream 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("i")
        set.add("am an")
        set.add("author")
          
        // Converting set to Stream 
        val stream = set.toStream
          
        // Displays Stream 
        println(stream)
      
    }
}
Output:
Stream(author, ?)
