toList()方法用於返回由TreeSet的所有元素組成的列表。
函數定義: def toList: List[A]
返回類型: It returns a list consisting of all the elements of the TreeSet.
範例1:
// Scala program of toList()
// method
// Import TreeSet
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(3, 1, 5, 2, 4)
// Print the TreeSet
println(t1)
// Applying toList method
val result = t1.toList
// Display output
print("Elements in the list: ")
for(elem <- result)
print(elem + " ")
}
}
輸出:
TreeSet(1, 2, 3, 4, 5) Elements in the list: 1 2 3 4 5
範例2:
// Scala program of toList()
// method
// Import TreeSet
import scala.collection.mutable._
// 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 toList method
val result = t1.toList
// Display output
print("Elements in the list: ")
for(elem <- result)
print(elem + " ")
}
}
輸出:
TreeSet(a, e, i, o, u) Elements in the list: a e i o u
