Scala SortedSet +() 方法示例
+()方法用于创建带有附加元素的新 SortedSet,除非该元素已经存在。
Method Definition: def +(elem: A): SortedSet[A]
Return Type: It returns a new SortedSet with an additional element unless the element is already present.
示例 #1:
// Scala program of +()
// method
import scala.collection.immutable.SortedSet
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a SortedSet
val s1 = SortedSet(1, 2, 3, 4, 6, 7)
// Applying +() method
val result = s1.+(5)
// Display output
print(result)
}
}
输出:
TreeSet(1, 2, 3, 4, 5, 6, 7)
示例 #2:
// Scala program of +()
// method
import scala.collection.immutable.SortedSet
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a SortedSet
val s1 = SortedSet(41, 12, 23, 43, 1, 72)
// Applying +() method
val result = s1.+(100)
// Display output
print(result)
}
}
输出:
TreeSet(1, 12, 23, 41, 43, 72, 100)
