带有示例的 Scala SortedMap empty() 方法

empty()方法用于使 SortedMap 为空。

示例 #1:

// Scala program of empty()
// method
import scala.collection.immutable.SortedMap
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs" -> 2)
          
        // Applying empty method
        val result = m1.empty
          
        // Displays output
        println(result)
      
    }
}
输出:
Map()

示例 #2:

// Scala program of empty()
// method
import scala.collection.immutable.SortedMap
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating an empty SortedMap
        val m1 = SortedMap("gopal" -> 10)
          
        // Applying empty method
        val result = m1.empty
          
        // Displays output
        println(result)
      
    }
}
输出:
Map()
