带有示例的 Scala SortedMap take() 方法

take()方法用于选择 SortedMap 的前“n”个元素。

Method Definition: def take(n: Int): SortedMap[A, B]

Return Type: It returns the first ‘n’ elements of the SortedMap.

示例 #1：

// Scala program of take()
// method
import scala.collection.immutable.SortedMap
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a SortedMap
        val m1 = SortedMap(3 -> "geeks", 4 -> "for", 2 -> "cs")
          
        // Applying take method
        val result = m1.take(2)
          
        // Displays output
        println(result)
      
    }
}

输出：

Map(2 -> cs, 3 -> geeks)

示例 #2：

// Scala program of take()
// method
import scala.collection.immutable.SortedMap
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a SortedMap
        val m1 = SortedMap(3 -> "geeks", 4 -> "for", 2 -> "cs")
          
        // Applying take method
        val result = m1.take(4)
          
        // Displays output
        println(result)
      
    }
}

输出：

Map(2 -> cs, 3 -> geeks, 4 -> for)
