Scala 不可变 TreeSet toBuffer() 方法
在 Scala 不可变 TreeSet 类中, toBuffer()方法用于返回由 TreeSet 的所有元素组成的缓冲区。
Method Definition: def toBuffer[B >: A]: Buffer[B]
Return Type: It returns a buffer consisting of all the elements of the TreeSet.
示例 #1:
// Scala program of toBuffer()
// 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 toBuffer method
val result = t1.toBuffer
// Display output
print("Elements in the buffer: ")
for(elem <- result)
print(elem + " ")
}
}
输出:
TreeSet(1, 2, 3, 4, 5)
Elements in the buffer: 1 2 3 4 5
示例 #2:
// Scala program of toBuffer()
// 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 toBuffer method
val result = t1.toBuffer
// Display output
print("Elements in the buffer: ")
for(elem <- result)
print(elem + " ")
}
}
输出:
TreeSet(a, e, i, o, u)
Elements in the buffer: a e i o u
