Scala ListSet filter() method with example
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()
