Scala Iterator drop() method with example

The drop() method belongs to the concrete value member of the class Abstract Iterator. It is defined in the classes Iterator and IterableOnceOps. It is utilized to move the iterator n places ahead and if n is greater than the iterator’s length, then it will throw an exception.

Method Definition : def drop(n: Int): Iterator[A]

Where, n is the number of elements to be dropped from the stated iterator.

Return Type : It returns all the elements of the stated iterator except the first n ones.

// Scala program of drop()

// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating an Iterator 
        val iter = Iterator(4, 6, 10, 11, 13)
          
        // Applying drop method
        val x = iter.drop(4)
          
        // Applying next method
        val result = x.next()
          
        // Displays output
        println(result)
      
    }
