Scala ListSet filter() method with example

Last Updated : 13 Feb, 2023

In Scala ListSet, filter() method is utilized to select all elements of the listSet which satisfies a stated predicate.

Method Definition: def filter(p: (A) => Boolean): ListSet[A] Return Type: It returns a new listset consisting all the elements of the listset which satisfies the given predicate.

Example 1:

Scala

// Scala program of filter() 
// method 
import scala.collection.immutable._
// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating listset
        val m1 = ListSet(1, 2, 3, 4, 5, 7)
        
        // Applying filter method 
        val result = m1.filter(_>2) 
        
        // Displays output 
        println(result) 
    
    } 
}

Output:

ListSet(3, 4, 5, 7)

Example 2:

Scala

// Scala program of filter() 
// method 
import scala.collection.immutable._
// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating listset
        val m1 = ListSet(1, 2, 3, 4, 5, 7)
        
        // Applying filter method 
        val result = m1.filter(_<1) 
        
        // Displays output 
        println(result) 
    
    } 
}

Output:

ListSet()
