Scala 不可变 TreeSet toString() 方法

在 Scala 不可变 TreeSet 类中， toString()方法用于返回 TreeSet 对象的字符串表示形式。

Method Definition: def toString(): String

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

示例 #1：

// Scala program of toString() 
// method 
  
// Import TreeSet
import scala.collection.immutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating TreeSet
        val t1 = TreeSet(1, 2, 3, 4, 5, 6)  
            
        // Print the TreeSet 
        println(t1) 
          
        // Applying toString method  
        val result = t1.toString
            
        // Display output 
        print("String representation of the TreeSet object: " + result) 
          
    } 
} 

输出：

TreeSet(1, 2, 3, 4, 5, 6)
String representation of the TreeSet object: TreeSet(1, 2, 3, 4, 5, 6)

示例 #2：

// Scala program of toString() 
// method 
  
// Import TreeSet
import scala.collection.immutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating TreeSet
        val t1 = TreeSet("u", "a", "i", "o", "e") 
            
        // Print the TreeSet 
        println(t1) 
          
        // Applying toString method  
        val result = t1.toString
            
        // Display output 
        print("String representation of the TreeSet object: " + result) 
          
    } 
} 

输出：

TreeSet(a, e, i, o, u)
String representation of the TreeSet object: TreeSet(a, e, i, o, u)
