带有示例的 Scala TreeSet toMap() 方法
toMap()方法用于返回由 TreeSet 的所有元素组成的地图。
Method Definition: def toMap[T, U]: Map[T, U]
Return Type: It returns a map consisting of all the elements of the TreeSet.
示例 #1:
// Scala program of toMap()
// method
// Import TreeSet
import scala.collection.mutable._
// 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 toMap method
val result = t1.toMap
// Display output
print("Elements in the Map: " + result)
}
}
输出:
TreeSet((1, 2), (3, 4), (5, 6))
Elements in the Map: Map(1 -> 2, 3 -> 4, 5 -> 6)
示例 #2:
// Scala program of toMap()
// 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", "f"))
// Print the TreeSet
println(t1)
// Applying toMap method
val result = t1.toMap
// Display output
print("Elements in the Map: " + result)
}
}
输出:
TreeSet((e, f), (i, o), (u, a))
Elements in the Map: Map(e -> f, i -> o, u -> a)
