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

Example #1:

// Scala program of dropWhile()
// method

// Creating object
object GfG
{

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

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

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

        // Displays output
        println(result)

    }
}

Output:

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

Example #2:

// Scala program of dropWhile()
// method

// Creating object
object GfG
{

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

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

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

        // Displays output
        println(result)

    }
}

Output:
