In Scala mutable collections, SortedSet filter() method is utilized to select all elements of the SortedSet which satisfies a stated predicate.
Method Definition: def filter(p: (A) => Boolean): SortedSet[A] Return Type: It returns a TreeSet containing all the elements of the SortedSet which satisfies the given predicate.
Example #1:
// Scala program of filter() 
// method 
import scala.collection.mutable.SortedSet 
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating a SortedSet 
        val s1 = SortedSet(5, 12, 3, 13
          
        // Applying filter method 
        val result = s1.filter(_ < 10
          
        // Displays output 
        println(result) 
      
    

                    
Output:
TreeSet(3, 5)
Example #2:
// Scala program of filter() 
// method 
import scala.collection.mutable.SortedSet 
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating a SortedSet 
        val s1 = SortedSet(5, 12, 3, 13
          
        // Applying filter method 
        val result = s1.filter(_ < 3
          
        // Displays output 
        println(result) 
      
    

                    
Output:
TreeSet()
