Scala Mutable SortedSet foreach() method
In Scala mutable collections, SortedSet foreach() method is utilized to apply the given function to all the elements of the SortedSet.
Method Definition: def foreach(f: (A) => Unit): Unit
Return Type: It returns all the elements of the SortedSet after applying the given function to each of them.
Example #1:
// Scala program of foreach() // method import scala.collection.mutable.SortedSet // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a SortedSet val s1 = SortedSet(13, 22, 19, 21) // Applying foreach method s1.foreach(x => println(x)) } } |
Output:
13 19 21 22
Example #2:
// Scala program of foreach() // method import scala.collection.mutable.SortedSet // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a SortedSet val s1 = SortedSet(5, 7, 8, 3, 2) // Applying foreach method s1.foreach(x => println(x + " times " + x + " = " + x*x)) } } |
Output:
2 times 2 = 4 3 times 3 = 9 5 times 5 = 25 7 times 7 = 49 8 times 8 = 64
