Scala TreeSet size() method with example
The size() method is utilized to return the number of elements present in the TrreSet.
Method Definition: def size: Int
Return Type: It returns the number of elements present in the TreeSet.
Example #1:
// Scala program of size() // method // Import TreeSetimport scala.collection.mutable._ // 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 size method val result = t1.size // Displays output print("Size of the TreeSet: " + result) } } |
Output:
TreeSet(1, 2, 3, 4, 5) Size of the TreeSet: 5
Example #2:
// Scala program of size() // method // Import TreeSetimport scala.collection.mutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating TreeSet val t1 = TreeSet(3, 1, 5, 2, 4, 10, 6, 9, 7, 8) // Print the TreeSet println(t1) // Applying size method val result = t1.size // Displays output print("Size of the TreeSet: " + result) } } |
Output:
TreeSet(1, 2, 3, 4, 5, 6, 7, 8, 9, 10) Size of the TreeSet: 10
