Scala Map drop() method with example

The drop() method is utilized to delete the first ‘n’ elements.

Method Definition: def drop(n: Int): Map[A, B]

Return Type: It returns all the elements of the map except the first ‘n’ elements.

Example #1:

// Scala program of drop()
// method

// Creating object
object GfG
{

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

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

        // Applying drop method
        val result = m1.drop(1)

        // Displays output
        println(result)

    }
}

Output:

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

Example #2:

// Scala program of drop()
// method

// Creating object
object GfG
{

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

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

        // Applying drop method
        val result = m1.drop(1)

        // Displays output
        println(result)

    }
}

Output:

Map(for -> 3)

So, both the identical keys are removed from the map.
