Scala Stack size() 方法示例
在 Scala Stack class
中, size()方法用于返回堆栈中存在的元素数量。
Method Definition: def size: Int
Return Type: It returns the number of elements present in the stack.
示例 #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)
}
}
输出:
Stack(1, 2, 3, 4)
Size of the stack: 4
示例 #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)
}
}
输出:
Stack(a, e, i, o, u)
Size of the stack: 5
