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 program of filter() // method import scala.collection.immutable._// Creating object object GfG { // Main method def main(args:Array[String]) { // Creating litset val m1 = ListSet(1, 2, 3, 4, 5, 7) // Applying filter method val result = m1.filter(_>2) // Displays output println(result) } } |

filter_none
Output:
ListSet(3, 4, 5, 7)
Example 2:
// Scala program of filter() // method import scala.collection.immutable._// Creating object object GfG { // Main method def main(args:Array[String]) { // Creating litset val m1 = ListSet(1, 2, 3, 4, 5, 7) // Applying filter method val result = m1.filter(_<1) // Displays output println(result) } } |
