// 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 toString method
        val result = m1.toString
          
        // Displays output
        println(result)
      
    }
}

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

示例 #2：

// Scala program of toString()
// 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 toString method
        val result = m1.toString
