Scala Map drop() method with example
  • Last Updated : 13 Aug, 2019

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.
