Scala Stack clone() 方法与示例

在 Scala Stack class中， clone()方法用于创建给定堆栈的副本。

Method Definition: def clone(): Stack[A]

Return Type: It return a new stack which is a copy of the given stack.

示例 #1：

// Scala program of clone() 
// 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, 5)  
            
        // Print the stack 
        println(s1) 
          
        // Applying clone method  
        val result = s1.clone  
            
        // Displays output  
        print("Clone of the stack: " + result)
    } 
} 

输出：

Stack(1, 2, 3, 4, 5)
Clone of the stack: Stack(1, 2, 3, 4, 5)

示例 #2：

// Scala program of clone() 
// method 
  
// Import Stack 
import scala.collection.mutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating stack  
        val s1 = Stack(3, 4, 5, 6, 7, 8)  
            
        // Print the stack 
        println(s1) 
          
        // Applying clone method  
        val result = s1.clone  
            
        // Displays output  
        print("Clone of the stack: " + result)
    } 
} 

输出：

Stack(3, 4, 5, 6, 7, 8)
Clone of the stack: Stack(3, 4, 5, 6, 7, 8)
