Scala TreeSet intersect() 方法示例
在 Scala 的 TreeSet 类中, intersect() 方法用于返回一个新的 TreeSet,其中包含出现在给定 TreeSet 中的元素。
方法定义:def intersect[B >: A](that: collection.Seq[B]): TreeSet[A]
返回类型:它返回一个新的 TreeSet,其中包含出现在给定 TreeSet 中的元素。
示例 #1:
// Scala program of intersect()
// method
// Import TreeSet
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSets
val t1 = TreeSet(1, 3, 2, 7, 6, 5)
val t2 = TreeSet(11, 3, 12, 7, 16, 5)
// Print the TreeSets
println("t1: " + t1)
println("t2: " + t2)
// Applying intersect() method
val result = t1.intersect(t2)
// Displays output
println("TreeSet with common elements: " + result)
}
}
t1: TreeSet(1, 2, 3, 5, 6, 7)
t2: TreeSet(3, 5, 7, 11, 12, 16)
TreeSet with common elements: TreeSet(3, 5, 7)
示例 #2:
// Scala program of intersect()
// method
// Import TreeSet
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSets
val t1 = TreeSet(1, 3, 2, 7, 6, 5)
val t2 = TreeSet(1, 13, 2, 17, 16, 5)
// Print the TreeSets
println("t1: " + t1)
println("t2: " + t2)
// Applying intersect() method
val result = t1.intersect(t2)
// Displays output
println("TreeSet with common elements: " + result)
}
}
t1: TreeSet(1, 2, 3, 5, 6, 7)
t2: TreeSet(1, 2, 5, 13, 16, 17)
TreeSet with common elements: TreeSet(1, 2, 5)
