Scala TreeSet copyToArray() method with example
  • Last Updated : 07 Oct, 2020

In Scala TreeSet class, the copyToArray() method is utilized in copying the elements of the TreeSet to an Array.

Method Definition: def copyToArray[B >: A](xs: Array[B], start: Int, len: Int): Int

Parameters:
xs: It denotes the array where elements are copied.
start: It denotes the starting index for the copy to takes place. Its default value is 0.
len: It denotes the number of elements to copy. Its default value is the length of the set.

Return Type: It returns the elements of the set to an array.

Example #1:






// Scala program of copyToArray() 
// method 
  
// Import TreeSet
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating TreeSet
        val t1 = TreeSet(2, 1, 3, 4, 5
          
        // Print the TreeSet
        println(t1
          
        // Creating an array 
        val arr = Array(0, 0, 0, 0, 0)
          
        // Applying copyToArray() method  
        t1.copyToArray(arr)
          
        // Displays output 
        println("Elements in the array: ")
          
        for(elem <- arr)  
            print(elem + " "
          
    
Output:
TreeSet(1, 2, 3, 4, 5)
Elements in the array: 
1 2 3 4 5

Example #2:




// Scala program of copyToArray() 
// method 
  
// Import TreeSet
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating TreeSet
        val t1 = TreeSet(2, 1, 3, 4, 5
          
        // Print the TreeSet
        println(t1
          
        // Creating an array 
        val arr = Array(0, 0, 0, 0, 0)
          
        // Applying copyToArray() method  
        t1.copyToArray(arr, 1, 2)
          
        // Displays output 
        println("Elements in the array: ")
          
        for(elem <- arr)  
            print(elem + " "
          
    
Output:
TreeSet(1, 2, 3, 4, 5)
Elements in the array: 
0 1 2 0 0
