Scala 不可变 TreeSet takeRight() 方法
在 Scala 不可变 TreeSet 类中, takeRight()方法用于返回由 TreeSet 的最后“n”个元素组成的 TreeSet。
Method Definition: def takeRight(n: Int):TreeSet[A]
Return Type: It returns a TreeSet consisting of the last ‘n’ elements of the TreeSet.
示例 #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)
}
}
输出:
TreeSet(1, 2, 3, 4, 5)
TreeSet containing last two elements: TreeSet(4, 5)
示例 #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)
}
}
输出:
TreeSet(1, 2, 3, 4, 5)
TreeSet containing last three elements: TreeSet(3, 4, 5)
