Program to convert Java Set of Strings to a String in Scala

Last Updated : 03 Jan, 2020

A java Set of Strings can be converted to a String in Scala by utilizing toString 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 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 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 a String 
        val str = set.toString 
          
        // Displays output 
        println(str) 
          
    } 
} 

Output:

[geeks, for]

Here, the duplicate elements are eliminated and the resultant order of the elements in set is same as stated above.
Example:2#

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