Scala 不可变 TreeSet take() 方法
在 Scala 不可变 TreeSet 类中, take()方法用于返回由 TreeSet 的前“n”个元素组成的 TreeSet。
Method Definition: def take(n: Int): TreeSet[A]
Return Type: It returns a TreeSet consisting of the first ‘n’ elements of the TreeSet.
示例 #1:
// Scala program of take()
// 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 take method
val result = t1.take(2)
// Displays output
print("TreeSet containing first two elements: " + result)
}
}
输出:
TreeSet(1, 2, 3, 4, 5)
TreeSet containing first two elements: TreeSet(1, 2)
示例 #2:
// Scala program of take()
// 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 take method
val result = t1.take(3)
// Displays output
print("TreeSet containing first three elements: " + result)
}
}
输出:
TreeSet(1, 2, 3, 4, 5)
TreeSet containing first three elements: TreeSet(1, 2, 3)
