带有示例的 Scala Queue toMap() 方法
toMap()方法用于返回由队列的所有元素组成的映射。
Method Definition: def toMap[T, U]: Map[T, U]
Return Type: It returns a map consisting of all the elements of the queue.
示例 #1:
// Scala program of toMap()
// 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, 6))
// Print the queue
println(q1)
// Applying toMap method
val result = q1.toMap
// Display output
print("Elements in the Map: " + result)
}
}
输出:
Queue((1, 2), (3, 4), (5, 6))
Elements in the Map: Map(1 -> 2, 3 -> 4, 5 -> 6)
示例 #2:
// Scala program of toMap()
// 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, 3))
// Print the queue
println(q1)
// Applying toMap method
val result = q1.toMap
// Display output
print("Elements in the Map: " + result)
}
}
输出:
Queue((5, 2), (13, 7), (1, 3))
Elements in the Map: Map(5 -> 2, 13 -> 7, 1 -> 3)
