极客教程Scala TreeSet intersect()方法及示例
在Scala TreeSet类中， intersect() 方法被用来返回一个新的TreeSet，该TreeSet由同时存在于给定TreeSet中的元素组成。
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，它由同时存在于给定TreeSet中的元素组成。
例子 #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)
}
}
输出。
t1: TreeSet(1, 2, 3, 5, 6, 7)
t2: TreeSet(3, 5, 7, 11, 12, 16)
TreeSet with common elements: TreeSet(3, 5, 7)
例子#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)
}
}
输出。
t1: TreeSet(1, 2, 3, 5, 6, 7)
t2: TreeSet(1, 2, 5, 13, 16, 17)
TreeSet with common elements: TreeSet(1, 2, 5)
