在 Scala Stack class
,則使用sum()方法返回堆棧中所有元素的總和。
函數定義: def sum: A
返回類型: It returns the sum of all the elements of the stack.
範例1:
// Scala program of sum()
// method
// Import Stack
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stack
val s1 = Stack(1, 2, 3, 4, 5)
// Print the stack
println(s1)
// Applying sum method
val result = s1.sum
// Display output
print("Sum of all elements: " + result)
}
}
輸出:
Stack(1, 2, 3, 4, 5) Sum of all elements: 15
範例2:
// Scala program of sum()
// method
// Import Stack
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stack
val s1 = Stack(5, 2, 13, 7, 1)
// Print the stack
println(s1)
// Applying sum method
val result = s1.sum
// Display output
print("Sum of all elements: " + result)
}
}
輸出:
Stack(5, 2, 13, 7, 1) Sum of all elements: 28
