Scala Queue take() 方法示例

take()方法用于返回由队列的前“n”个元素组成的队列。

示例 #1:

// Scala program of take() 
// 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 take method 
        val result = q1.take(2)
          
        // Display output
        print("Queue containing first two elements: " + result)
          
    } 
} 
输出:
Queue(5, 2, 13, 7, 1)
Queue containing first two elements: Queue(5, 2)

示例 #2:

// Scala program of take() 
// 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 take method 
        val result = q1.take(3)
          
        // Display output
        print("Queue containing first three elements: " + result)
          
    } 
} 
输出:
Queue(5, 2, 13, 7, 1)
Queue containing first three elements: Queue(5, 2, 13)
