Scala Stack toBuffer() 方法与示例
在 Scala Stack class
中, toBuffer()方法用于返回由堆栈的所有元素组成的缓冲区。
Method Definition: def toBuffer[B >: A]: Buffer[B]
Return Type: It returns a buffer consisting of all the elements of the stack.
示例 #1:
// Scala program of toBuffer()
// 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 toBuffer method
val result = s1.toBuffer
// Display output
print("Elements in the buffer: ")
for(elem <- result)
print(elem + " ")
}
}
输出:
Stack(5, 2, 13, 7, 1)
Elements in the buffer: 5 2 13 7 1
示例 #2:
// Scala program of toBuffer()
// 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 toBuffer method
val result = s1.toBuffer
// Display output
print("Elements in the buffer: ")
for(elem <- result)
print(elem + " ")
}
}
输出:
Stack(1, 2, 3, 4, 5)
Elements in the buffer: 1 2 3 4 5
