Scala Mutable SortedMap toSet() 方法与示例

toSet()方法用于显示来自 Scala SortedMap 的集合。

Method Definition: def toSet: Set[A]

Return Type: It returns a set from the stated SortedMap.

示例 #1：

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

输出：

Set((3, geeks), (4, for))

示例 #2：

// Scala program of toSet()
// method
import scala.collection.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 toSet method
        val result = m1.toSet
          
        // Displays output
        println(result)
          
    }
}

输出：

Set((2, cs), (3, geeks), (4, for))
