Scala Mutable SortedSet copyToArray() 方法

在 Scala Mutable 集合中， copyToArray()方法用于将 SortedSet 的元素复制到数组中。

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

Parameters:
xs: denotes the array where elements are copied.
start: 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 length of the SortedSet.

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

示例 #1：

// Scala program of copyToArray()
// method
import scala.collection.mutable.SortedSet 
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating SortedSets 
        val s1 = SortedSet(1, 2, 3)
          
        val arr: Array[Int] = Array(0, 0, 0, 0, 0)
          
        // Applying copyToArray method 
        s1.copyToArray(arr) 
          
        // Displays output 
        for(elem <- arr)  
        println(elem) 
      
    } 
} 

输出：

        val arr: Array[Int] = Array(0, 0, 0, 0, 0)
          
        // Applying copyToArray method 
        s1.copyToArray(arr, 1, 2) 
          
        // Displays output 
        for(elem <- arr)  
        println(elem) 
      
    } 
}
