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 TreeSet import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating TreeSet val t 1 = TreeSet( 3 , 1 , 5 , 2 , 4 ) // Print the TreeSet println(t 1 ) // Applying size method val result = t 1 .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 TreeSet import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating TreeSet val t 1 = TreeSet( 3 , 1 , 5 , 2 , 4 , 10 , 6 , 9 , 7 , 8 ) // Print the TreeSet println(t 1 ) // Applying size method val result = t 1 .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
