在Scala不變樹集類中,size()方法用於返回TrreSet中存在的元素數。
Method Definition: def size:Int
Return Type: It returns the number of elements present in the TreeSet.
範例1:
// Scala program of size()
// 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 size method
val result = t1.size
// Displays output
print("Size of the TreeSet:" + result)
}
}
輸出:
TreeSet(1, 2, 3, 4, 5) Size of the TreeSet:5
範例2:
// Scala program of size()
// 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, 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)
}
}
輸出:
TreeSet(1, 2, 3, 4, 5, 6, 7, 8, 9, 10) Size of the TreeSet:10
