The dropWhile() method is utilized to delete the elements until the stated condition is satisfied.
Method Definition: def dropWhile(p: ((A, B)) => Boolean): SortedMap[A, B] Return Type: It returns the longest suffix of elements of the stated SortedMap whose first element does not satisfies the predicate p.
Example #1:
// Scala program of dropWhile()
// method
import scala.collection.SortedMap
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs" -> 2)
          
        // Applying dropWhile method
        val result = m1.dropWhile(z=>false
          
        // Displays output
        println(result)
      
    }
}

                    
Output:
Map(cs -> 2, for -> 3, geeks -> 5)
Example #2:
// Scala program of dropWhile()
// method
import scala.collection.SortedMap
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs" -> 2)
          
        // Applying dropWhile method
        val result = m1.dropWhile(z=>true
          
        // Displays output
        println(result)
          
    }
}
