Scala TreeSet take() 方法与示例

take()方法用于返回由 TreeSet 的前“n”个元素组成的 TreeSet。

Method Definition: def take(n: Int): TreeSet[A]

Return Type: It returns a TreeSet consisting of the first ‘n’ elements of the TreeSet.

示例 #1：

// Scala program of take() 
// 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 take method  
        val result = t1.take(2)
            
        // Displays output  
        print("TreeSet containing first two elements: " + result) 
          
    } 
} 

输出：

TreeSet(1, 2, 3, 4, 5)
TreeSet containing first two elements: TreeSet(1, 2)

示例 #2：

// Scala program of take() 
// 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 take method  
        val result = t1.take(3)
            
        // Displays output  
        print("TreeSet containing first three elements: " + result) 
          
    } 
} 

输出：

TreeSet(1, 2, 3, 4, 5)
TreeSet containing first three elements: TreeSet(1, 2, 3)
