Scala Mutable SortedMap dropWhile() method with example
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 m 1 = SortedMap( "Beginner" - > 5 , "for" - > 3 , "cs" - > 2 ) // Applying dropWhile method val result = m 1 .dropWhile(z => false ) // Displays output println(result) } } |
Output:
Map(cs -> 2, for -> 3, Beginner -> 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 m 1 = SortedMap( "Beginner" - > 5 , "for" - > 3 , "cs" - > 2 ) // Applying dropWhile method val result = m 1 .dropWhile(z => true ) // Displays output println(result) } } |
Output:
Map()
