In Scala mutable collections, SortedSet 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 program of filter() // method import scala.collection.mutable.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 program of filter() // method import scala.collection.mutable.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()
