Program to convert Java Set of characters to Sequence in Scala

Last Updated : 14 Jan, 2020

A java Set of characters can be converted to a Sequence in Scala by utilizing toSeq 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

// Scala program to convert Java set 
// to Sequence 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 character in Java
        val set = new java.util.HashSet[Char]()
        
        // Adding characters to the set
        set.add('a')
        set.add('b')
        set.add('c')
        
        // Converting set to Sequence 
        val seq = set.toSeq
        
        // Displays Sequence 
        println(seq)
    
    }
}

Output:

ArrayBuffer(a, b, c)

Example:2#

Scala

// Scala program to convert Java set 
// to Sequence 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 character in Java
        val set = new java.util.HashSet[Char]()
        
        // Adding characters to the set
        set.add('d')
        set.add('b')
        set.add('c')
        
        // Converting set to Sequence 
        val seq = set.toSeq
        
        // Displays Sequence 
        println(seq)
    
    }
}

Output:

ArrayBuffer(b, c, d)
