带有示例的 Scala TreeSet takeRight() 方法

takeRight()方法用于返回由 TreeSet 的最后“n”个元素组成的 TreeSet。

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

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

示例 #1：

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

输出：

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

示例 #2：

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

输出：

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