Scala Mutable SortedMap transform() method with example

The transform() method is utilized to transform the elements of the SortedMap into a mutable SortedMap.

Method Definition: def transform(f: (K, V) => V): SortedMap.this.type

Return Type: It transforms all the elements of the SortedMap and returns them into a mutable SortedMap.

Example #1:

// Scala program of transform()
// method
import scala.collection.SortedMap

// Creating object
object GfG
{

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

        // Creating a SortedMap
        val m1 = SortedMap(3 -> "geeks", 4 -> "for", 2 -> "cs")

        // Applying transform method
        val result = m1.transform((key, value) => value.toUpperCase)

        // Displays output
        println(result)

    }
}

Output:

Map(2 -> CS, 3 -> GEEKS, 4 -> FOR)

Example #2:

// Scala program of transform()
// method
import scala.collection.SortedMap

// Creating object
object GfG
{

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

        // Creating a SortedMap
        val m1 = SortedMap(3 -> "geeks", 4 -> "for", 4 -> "for")

        // Applying transform method
        val result = m1.transform((key, value) => value.toUpperCase)

        // Displays output
        println(result)

    }
}

Output:

Map(3 -> GEEKS, 4 -> FOR)
