En Scala inmutable TreeSet class, el método –() se utiliza para restar elementos de un TreeSet a otro TreeSet.
Definición del método: def –(que: IterableOnce[A]): TreeSet[A]
Tipo de retorno: Devuelve un nuevo TreeSet que contiene el elemento de A – B TreeSets.
Ejemplo 1:
// Scala program of --()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSets
val t1 = TreeSet("g", "e", "e", "k", "s")
val t2 = TreeSet("a", "e", "i", "o", "u")
// Print the TreeSets
println(t1)
println(t2)
// Applying --() method
val result = t1 -- t2
// Display output
print("Combined TreeSet: " + result)
}
}
Producción:
TreeSet(e, g, k, s) TreeSet(a, e, i, o, u) Combined TreeSet: TreeSet(g, k, s)
Ejemplo #2:
// Scala program of --()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSets
val t1 = TreeSet(1, 6, 3, 2, 5)
val t2 = TreeSet(2, 1, 5, 4, 1)
// Print the TreeSets
println(t1)
println(t2)
// Applying --() method
val result = t1 -- t2
// Display output
print("Combined TreeSet: " + result)
}
}
Producción:
TreeSet(1, 2, 3, 5, 6) TreeSet(1, 2, 4, 5) Combined TreeSet: TreeSet(3, 6)
