在 Scala 中不可变TreeSet class
, 这+()方法用于将元素添加到TreeSet,除非它已经存在。
函数定义: def +(elem: A): TreeSet[A]
返回类型: It returns a new TreeSet with an additional element unless the element is already present.
示例#1:
// Scala program of +()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSets
val t1 = TreeSet("a", "e", "i", "o")
// Print the TreeSets
println(t1)
// Applying +() method
val result = t1 + ("u")
// Display output
print("After adding an element: " + result)
}
}
输出:
TreeSet(a, e, i, o) After adding an element: TreeSet(a, e, i, o, u)
示例#2:
// Scala program of +()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSets
val t1 = TreeSet(2, 1, 5, 4, 1)
// Print the TreeSets
println(t1)
// Applying +() method
val result = t1 + (3)
// Display output
print("After adding an element: " + result)
}
}
输出:
TreeSet(1, 2, 4, 5) After adding an element: TreeSet(1, 2, 3, 4, 5)
