Scala TreeSet dropWhile() method with example Last Updated : 02 Nov, 2019 Comments Improve Suggest changes Like Article Like Report In Scala TreeSet class, the dropWhile() method is utilized to drop the longest prefix from the front which satisfies a given predicate in a TreeSet. Method Definition: def dropWhile(p: (A) => Boolean): TreeSet[A] Return Type: It returns a new TreeSet that consists of elements after dropping the longest prefix satisfying the given predicate. Example #1: Scala // Scala program of dropWhile() // method // Import TreeSet import scala.collection.mutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating TreeSet val t1 = TreeSet(2, 4, 6, 7, 8, 9) // Print the TreeSet println(t1) // Applying dropWhile() method val result = t1.dropWhile(x => {x % 2 == 0}) // Displays output println("TreeSet after using dropWhile() method: " + result) } } Output: TreeSet(2, 4, 6, 7, 8, 9) TreeSet after using dropWhile() method: TreeSet(7, 8, 9) Example #2: Scala // Scala program of dropWhile() // method // Import TreeSet import scala.collection.mutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating TreeSet val t1 = TreeSet(3, 5, 6, 7, 8, 9) // Print the TreeSet println(t1) // Applying dropWhile() method val result = t1.dropWhile(x => {x % 2 != 0}) // Displays output println("TreeSet after using dropWhile() method: " + result) } } Output: TreeSet(3, 5, 6, 7, 8, 9) TreeSet after using dropWhile() method: TreeSet(6, 7, 8, 9) Comment More infoAdvertise with us Next Article Scala TreeSet dropWhile() method with example R rupesh_rao Follow Improve Article Tags : Scala Scala Scala-Method scala-collection Similar Reads Scala Set dropWhile() method with example The dropWhile() method is utilized to drop the longest prefix of elements from the set that satisfies the stated condition.
