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

範例2:

// Scala program of takeRight()  
// method  
  
// Import TreeSet 
import scala.collection.mutable._
