在 Scala Stack class
,則使用size()方法返回堆棧中存在的元素數。
函數定義: def size: Int
返回類型: It returns the number of elements present in the stack.
範例1:
// Scala program of size()
// 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)
// Print the stack
println(s1)
// Applying size method
val result = s1.size
// Display output
print("Size of the stack: " + result)
}
}
輸出:
Stack(1, 2, 3, 4) Size of the stack: 4
範例2:
// Scala program of size()
// method
// Import Stack
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stack
val s1 = Stack("a", "e", "i", "o", "u")
// Print the stack
println(s1)
// Applying size method
val result = s1.size
// Display output
print("Size of the stack: " + result)
}
}
輸出:
Stack(a, e, i, o, u) Size of the stack: 5
