返回類型: It returns a stack consisting of the first ‘n’ elements of the stack.



範例1:

// Scala program of take()  
// method  
  
// Import Stack  
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating stack 
        val s1 = Stack(1, 2, 3, 4)  
          
        // Print the stack  
        println(s1)  
           
        // Applying take method   
        val result = s1.take(2) 
          
        // Display output  
        print("Stack containing first two elements: " + result)  
         
    }  
} 
輸出:
Stack(1, 2, 3, 4)
Stack containing first two elements: Stack(1, 2)

範例2:

// Scala program of take()  
// method  
  
// Import Stack  
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating stack 
        val s1 = Stack(1, 2, 3, 4)  
          
        // Print the stack  
        println(s1)  
           
        // Applying take method   
        val result = s1.take(3) 
          
        // Display output  
        print("Stack containing first three elements: " + result)
