Scala Mutable SortedMap dropWhile() method with example

The dropWhile() method is utilized to delete the elements until the stated condition is satisfied.

Method Definition: def dropWhile(p: ((A, B)) => Boolean): SortedMap[A, B]

Return Type: It returns the longest suffix of elements of the stated SortedMap whose first element does not satisfies the predicate p.

Example #1:

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

// Creating object
object GfG
{

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

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

        // Applying dropWhile method
        val result = m1.dropWhile(z=>false)

        // Displays output
        println(result)

    }
}

Output:

Map(cs -> 2, for -> 3, geeks -> 5)

Example #2:

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

// Creating object
object GfG
{

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

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

        // Applying dropWhile method
        val result = m1.dropWhile(z=>true)

        // Displays output
        println(result)

    }
}

Output:

Map()
