Scala SortedSet filter() method with example

Last Updated : 03 Nov, 2019

The 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

// Scala program of filter() 
// method 
import scala.collection.immutable.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

// Scala program of filter() 
// method 
import scala.collection.immutable.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()
