带有示例的 Scala TreeSet size() 方法
size()方法用于返回 TrreSet 中存在的元素数量。
Method Definition: def size: Int
Return Type: It returns the number of elements present in the TreeSet.
示例 #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 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)
}
}
输出:
TreeSet(1, 2, 3, 4, 5)
Size of the TreeSet: 5
示例 #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 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)
}
}
输出:
TreeSet(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
Size of the TreeSet: 10
