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

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

Return Type: It returns a new queue with all the elements except the first ‘n’ ones.

Example #1:

// Scala program of drop()  
// method  
  
// Import Queue   
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating queues  
        val q1 = Queue(1, 2, 3, 4, 5)  
          
        // Print the queue 
        println(q1) 
          
        // Applying drop method  
        val result = q1.drop(2)  
          
        // Displays output  
        print("Queue after drop(2) method: " + result) 
    }  
}  

Output:

Queue(1, 2, 3, 4, 5)
Queue after drop(2) method: Queue(3, 4, 5)

Example #2:

// Scala program of drop()  
// method  
  
// Import Queue   
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating queues  
        val q1 = Queue(1, 2, 3, 4, 5)  
          
        // Print the queue 
        println(q1) 
          
        // Applying drop method  
        val result = q1.drop(3)  
          
        // Displays output  
        print("Queue after drop(3) method: " + result) 
    }  
}  

Output:

Queue(1, 2, 3, 4, 5)
Queue after drop(3) method: Queue(4, 5)
