带有示例的 Scala TreeSet toList() 方法

toList()方法用于返回由 TreeSet 的所有元素组成的列表。

Method Definition: def toList: List[A]

Return Type: It returns a list consisting of all the elements of the TreeSet.

示例 #1：

// Scala program of toList() 
// method 
  
// Import TreeSet
import scala.collection.mutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating TreeSet
        val t1 = TreeSet(3, 1, 5, 2, 4)  
            
        // Print the TreeSet 
        println(t1) 
          
        // Applying toList method  
        val result = t1.toList
            
        // Display output 
        print("Elements in the list: ") 
            
        for(elem <- result) 
            print(elem + " ") 
              
    } 
} 

输出：

TreeSet(1, 2, 3, 4, 5)
Elements in the list: 1 2 3 4 5

示例 #2：

// Scala program of toList() 
// method 
  
// Import TreeSet
import scala.collection.mutable._
  
// 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 toList method  
        val result = t1.toList
            
        // Display output 
        print("Elements in the list: ") 
            
        for(elem <- result) 
            print(elem + " ") 
              
    } 
} 

输出：

TreeSet(a, e, i, o, u)
Elements in the list: a e i o u
