sum()方法用於返回TreeSet中所有元素的總和。
函數定義: def sum: A
返回類型: It returns the sum of all the elements of the TreeSet.
範例1:
// Scala program of sum()
// 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 sum method
val result = t1.sum
// Displays output
print("Sum of all the elements of the TreeSet: " + result)
}
}
輸出:
TreeSet(1, 2, 3, 4, 5) Sum of all the elements of the TreeSet: 15
範例2:
// Scala program of sum()
// 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, 7, 9)
// Print the TreeSet
println(t1)
// Applying sum method
val result = t1.sum
// Displays output
print("Sum of all the elements of the TreeSet: " + result)
}
}
輸出:
TreeSet(1, 3, 5, 7, 9) Sum of all the elements of the TreeSet: 25
