Scala Stack intersect() 方法与示例

在 Scala Stack class中， intersect()方法用于返回一个新堆栈，该堆栈由两个给定堆栈中都存在的元素组成。

Method Definition: def intersect[B >: A](that: collection.Seq[B]): Stack[A]

Return Type: It returns a new stack that consists of elements that are present in both the given stacks.

示例 #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 + " "))
          
    } 
} 

输出：

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

示例 #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) 
         
    } 
} 

输出：

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)
