在Scala不可变的TreeSet类中,toArray()用于返回由TreeSet的所有元素组成的数组。
Method Definition: def toArray:Array[A]
Return Type: It returns an array consisting of all the elements of the TreeSet.
范例1:
// Scala program of toArray()
// method
// Import TreeSet
import scala.collection.immutable._
// 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 toArray method
val result = t1.toArray
// Display output
print("Elements in the array:")
for(elem <- result)
print(elem + " ")
}
}
输出:
TreeSet(1, 2, 3, 4, 5) Elements in the array:1 2 3 4 5
范例2:
// Scala program of toArray()
// 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 toArray method
val result = t1.toArray
// Display output
print("Elements in the array:")
for(elem <- result)
print(elem + " ")
}
}
输出:
TreeSet(a, e, i, o, u) Elements in the array:a e i o u
