Scala Queue intersect()用法及代碼示例

intersect()方法用於返回一個新隊列，該隊列由兩個給定隊列中都存在的元素組成。

函數定義: def intersect[B >: A](that: collection.Seq[B]): Queue[A]

返回類型: It returns a new queue that consists of elements that are present in both the given queues.

範例1：

// Scala program of intersect()  
// method  
  
// Import Queue   
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating queues  
        val q1 = Queue(1, 3, 2, 7, 6, 5)  
          
        val q2 = Queue(1, 13, 2, 17, 6, 15)  
          
        // Print the queues 
        println("Queue_1: " + q1) 
          
        println("Queue_2: " + q2) 
          
        // Applying intersect method  
        val result = q1.intersect(q2) 
          
        // Display output 
        print("The elements in both the queues: ") 
          
        result.foreach(x => print(x + " ")) 
          
    }  
}

輸出：

Queue_1: Queue(1, 3, 2, 7, 6, 5)
Queue_2: Queue(1, 13, 2, 17, 6, 15)
The elements in both the queues: 1 2 6

範例2：

// Scala program of intersect()  
// method  
  
// Import Queue   
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating queues  
        val q1 = Queue(1, 3, 2, 7, 6, 5)  
          
        val q2 = Queue(11, 3, 12, 7, 16, 5)  
          
        // Print the queues 
        println("Queue_1: " + q1) 
          
        println("Queue_2: " + q2) 
          
        // Applying intersect method  
        val result = q1.intersect(q2) 
          
        // Display output 
        print("The elements in both the queues: " + result) 
          
    }  
}

輸出：

Queue_1: Queue(1, 3, 2, 7, 6, 5)
Queue_2: Queue(11, 3, 12, 7, 16, 5)
The elements in both the queues: Queue(3, 7, 5)
