带有示例的 Scala Stack tail() 方法

在 Scala Stack class中, tail()方法用于返回一个新堆栈,该堆栈由除第一个元素之外的所有元素组成。

示例 #1:

// Scala program of tail() 
// method 
  
// Import Stack 
import scala.collection.mutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating stack
        val s1 = Stack(1, 3, 2, 7, 6, 5) 
          
        // Print the stack 
        println(s1) 
           
        // Applying tail method  
        val result = s1.tail 
          
        // Display output 
        print("Elements of the queue except the first one: " + result) 
         
    } 
} 
输出:
Stack(1, 3, 2, 7, 6, 5)
Elements of the queue except the first one: Stack(3, 2, 7, 6, 5)

示例 #2:

// Scala program of tail() 
// method 
  
// Import Stack 
import scala.collection.mutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating stack
        val s1 = Stack(5, 3, 2, 7, 6, 1) 
          
        // Print the stack 
        println(s1) 
           
        // Applying tail method  
        val result = s1.tail 
          
        // Display output 
        print("Elements of the queue except the first one: " + result) 
         
    } 
} 
输出:
Stack(5, 3, 2, 7, 6, 1)
Elements of the queue except the first one: Stack(3, 2, 7, 6, 1)
