Scala Stack intersect()用法及代碼示例

在 Scala Stack class，則使用intersect()方法返回一個新堆棧，該堆棧由兩個給定堆棧中都存在的元素組成。

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

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

範例1：

// Scala program of intersect()  
// method  
  
// Import Stack  
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating stacks   
        val s1 = Stack(1, 3, 2, 7, 6, 5)  
          
        val s2 = Stack(1, 13, 2, 17, 6, 15) 
          
        // Print the stack  
        println("Stack_1: " + s1)  
            
        println("Stack_2: " + s2) 
            
        // Applying intersect method   
        val result = s1.intersect(s2)  
          
        // Display output  
        print("The elements in both the stacks: ")  
            
        result.foreach(x => print(x + " ")) 
          
    }  
}

輸出：

Stack_1: Stack(1, 3, 2, 7, 6, 5)
Stack_2: Stack(1, 13, 2, 17, 6, 15)
The elements in both the stacks: 1 2 6

範例2：

// Scala program of intersect()  
// method  
  
// Import Stack  
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating stacks   
        val s1 = Stack(1, 3, 2, 7, 6, 5)  
          
        val s2 = Stack(11, 3, 12, 7, 16, 5) 
          
        // Print the stack  
        println("Stack_1: " + s1)  
            
        println("Stack_2: " + s2) 
            
        // Applying intersect method   
        val result = s1.intersect(s2)  
          
        // Display output  
        print("The elements in both the stacks: " + result)  
         
    }  
}

輸出：

Stack_1: Stack(1, 3, 2, 7, 6, 5)
Stack_2: Stack(11, 3, 12, 7, 16, 5)
The elements in both the stacks: Stack(3, 7, 5)
