在Scala不可變TreeSet類中,使用takeRight()方法返回由TreeSet的最後‘n’個元素組成的TreeSet。
Method Definition: def takeRight(n:Int):TreeSet[A]
Return Type: It returns a TreeSet consisting of the last ‘n’ elements of the TreeSet.
範例1:
// Scala program of takeRight()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(3, 1, 5, 2, 4)
// Print the TreeSet
println(t1)
// Applying takeRight method
val result = t1.takeRight(2)
// Displays output
print("TreeSet containing last two elements:" + result)
}
}
輸出:
TreeSet(1, 2, 3, 4, 5) TreeSet containing last two elements:TreeSet(4, 5)
範例2:
// Scala program of takeRight()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(3, 1, 5, 2, 4)
// Print the TreeSet
println(t1)
// Applying takeRight method
val result = t1.takeRight(3)
// Displays output
print("TreeSet containing last three elements:" + result)
}
}
輸出:
TreeSet(1, 2, 3, 4, 5) TreeSet containing last three elements:TreeSet(3, 4, 5)
