Scala Mutable SortedMap mkString() method with a separator with example

This method is same as mkString() method but here a separator is also added.

Method Definition: def mkString(sep: String): String

Return Type: It returns the elements of the SortedMap as a string along with the separator between them.

Example #1:

// Scala program of mkString()
// method with a separator
import scala.collection.SortedMap


// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs" -> 2)

        // Applying mkString method
        val result = m1.mkString("/")

        // Displays output
        println(result)
    }
}

Output:

cs -> 2/for -> 3/geeks -> 5

Example #2:

// Scala program of mkString()
// method with a separator
import scala.collection.SortedMap

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "geeks" -> 5)

        // Applying mkString method
        val result = m1.mkString("/")

        // Displays output
        println(result)
    }
}
