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 m 1 = ListSet( 1 , 2 , 3 , 4 , 5 , 7 )
// Applying filter method
val result = m 1 .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 m 1 = ListSet( 1 , 2 , 3 , 4 , 5 , 7 )
// Applying filter method
val result = m 1 .filter( _ < 1 )
// Displays output
println(result)
}
} |
Output:
ListSet()
