The filter() method is utilized to select all elements of the SortedMap which satisfies a stated predicate.

Method Definition: def filter(p: ((A, B))=> Boolean): SortedMap[A, B]

Return Type: It returns a new SortedMap consisting all the elements of the SortedMap which satisfies the given predicate.

Example #1:




// Scala program of filter()
// method
import scala.collection.SortedMap
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3)
          
        // Applying filter method
        val result = m1.filter(x => x._1 == "geeks" && x._2 == 5)
          
        // Displays output
        println(result)
      
    }
}


Output:

Map(geeks -> 5)

Example #2:




// Scala program of filter()
// method
import scala.collection.SortedMap
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3)
          
        // Applying filter method
        val result = m1.filter(x => x._1 == "for" && x._2 == 5)
          
        // Displays output
        println(result)
      
    }
}


Output:

Map()

Here, an empty SortedMap is returned as none of the elements satisfy the stated predicate.
