带有示例的 Scala Queue toBuffer() 方法
toBuffer()方法用于返回由队列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 queue.
示例 #1:
// Scala program of toBuffer()
// method
// Import Queue
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a queue
val q1 = Queue(1, 2, 3, 4, 5)
// Print the queue
println(q1)
// Applying toBuffer method
val result = q1.toBuffer
// Display output
print("Elements in the buffer: ")
for(elem <- result)
print(elem + " ")
}
}
输出:
Queue(1, 2, 3, 4, 5)
Elements in the buffer: 1 2 3 4 5
示例 #2:
// Scala program of toBuffer()
// method
// Import Queue
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a queue
val q1 = Queue(5, 2, 13, 7, 1)
// Print the queue
println(q1)
// Applying toBuffer method
val result = q1.toBuffer
// Display output
print("Elements in the buffer: ")
for(elem <- result)
print(elem + " ")
}
}
输出:
Queue(5, 2, 13, 7, 1)
Elements in the buffer: 5 2 13 7 1
