Scala Stack toString() 方法与示例

在 Scala Stack class中， toString()方法用于返回堆栈对象的字符串表示形式。

Method Definition: def toString(): String

Return Type: It returns a string representation of the stack object.

示例 #1：

// Scala program of toString() 
// 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 toString method  
        val result = s1.toString
          
        // Display output 
        print("String representation of the stack object: " + result) 
           
    } 
} 

输出：

Stack(1, 2, 3, 4, 5)
String representation of the stack object: Stack(1, 2, 3, 4, 5)

示例 #2：

// Scala program of toString() 
// method 
  
// Import Stack 
import scala.collection.mutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating stack
        val s1 = Stack(5, 2, 13, 7, 1, 3) 
          
        // Print the stack 
        println(s1) 
           
        // Applying toString method  
        val result = s1.toString
          
        // Display output 
        print("String representation of the stack object: " + result) 
           
    } 
} 

输出：

Stack(5, 2, 13, 7, 1, 3)
String representation of the stack object: Stack(5, 2, 13, 7, 1, 3)
