带有示例的 Scala TreeSet drop() 方法
在 Scala TreeSet class
中, drop()方法用于删除 TreeSet 的前“n”个元素。
Method Definition: def drop(n: Int): TreeSet[A]
Return Type: It returns a new TreeSet with all the elements except the first ‘n’ ones.
示例 #1:
// Scala program of drop()
// method
// Import TreeSet
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(2, 4, 6, 7, 8, 9)
// Print the TreeSet
println(t1)
// Applying drop() method
val result = t1.drop(2)
// Displays output
println("TreeSet after using drop(2) method: " + result)
}
}
输出:
TreeSet(2, 4, 6, 7, 8, 9)
TreeSet after using drop(2) method: TreeSet(6, 7, 8, 9)
示例 #2:
// Scala program of drop()
// method
// Import TreeSet
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(2, 4, 6, 7, 8, 9)
// Print the TreeSet
println(t1)
// Applying drop() method
val result = t1.drop(3)
// Displays output
println("TreeSet after using drop(3) method: " + result)
}
}
输出:
TreeSet(2, 4, 6, 7, 8, 9)
TreeSet after using drop(3) method: TreeSet(7, 8, 9)
