def main(args : Array[String])
{
val t 1 = TreeSet( 1 , 3 , 2 , 7 , 6 , 5 )
println(t 1 )
val result = t 1 .filter(x => {x % 2 == 1 })
println( "Odd Elements: " + result)
}
}

Output:
TreeSet(1, 2, 3, 5, 6, 7)
Odd Elements: TreeSet(1, 3, 5, 7)
Example #2:
import scala.collection.immutable. _
object GfG
{
def main(args : Array[String])
{
val t 1 = TreeSet( 1 , 3 , 2 , 7 , 6 , 5 )
println(t 1 )
val result = t 1 .filter(x => {x % 2 == 0 })
println( "Even Elements: " + result)
