Scala 不可变 TreeSet toSeq() 方法
在 Scala 不可变 TreeSet 类中, toSeq()方法用于返回由 TreeSet 的所有元素组成的序列。
Method Definition: def toSeq: Seq[A]
Return Type: It returns a seq consisting of all the elements of the TreeSet.
示例 #1:
// Scala program of toSeq()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(1, 2, 3, 4, 5, 6)
// Print the TreeSet
println(t1)
// Applying toSeq method
val result = t1.toSeq
// Display output
print("Elements in the Seq: ")
for (ele <- result)
print(ele + " ")
}
}
输出:
TreeSet(1, 2, 3, 4, 5, 6)
Elements in the Seq: 1 2 3 4 5 6
示例 #2:
// Scala program of toSeq()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet("u", "a", "i", "o", "e")
// Print the TreeSet
println(t1)
// Applying toSeq method
val result = t1.toSeq
// Display output
print("Elements in the Seq: ")
for (ele <- result)
print(ele + " ")
}
}
输出:
TreeSet(a, e, i, o, u)
Elements in the Seq: a e i o u
