Scala immutable TreeSet toArray() method
In Scala immutable TreeSet class the toArray() is utilised to return an array consisting of all the elements of the TreeSet.
Method Definition: def toArray: Array[A]
Return Type: It returns an array consisting of all the elements of the TreeSet.
Example #1:
// Scala program of toArray() // method // Import TreeSet import scala.collection.immutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating TreeSet val t1 = TreeSet(3, 1, 5, 2, 4) // Print the TreeSet println(t1) // Applying toArray method val result = t1.toArray // Display output print("Elements in the array: ") for(elem <- result) print(elem + " ") } } |
Output:
TreeSet(1, 2, 3, 4, 5) Elements in the array: 1 2 3 4 5
Example #2:
// Scala program of toArray() // method // Import TreeSet import scala.collection.immutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating TreeSet val t1 = TreeSet("u", "a", "i", "o", "e") // Print the TreeSet println(t1) // Applying toArray method val result = t1.toArray // Display output print("Elements in the array: ") for(elem <- result) print(elem + " ") } } |
Output:
TreeSet(a, e, i, o, u) Elements in the array: a e i o u
