带有分隔符的 Scala TreeSet mkString() 方法和示例
mkString()方法用于在字符串中显示 TreeSet 的所有元素以及分隔符。
Method Definition: def mkString(sep: String): String
Return Type: It returns all the elements of the TreeSet in a string along with a separator.
示例 #1:
// Scala program of mkString()
// 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 mkString method
val result = t1.mkString(", ")
// Displays output
print("TreeSet: " + result)
}
}
输出:
TreeSet(1, 2, 3, 4, 5)
TreeSet: 1, 2, 3, 4, 5
示例 #2:
// Scala program of mkString()
// 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 mkString method
val result = t1.mkString(", ")
// Displays output
print("TreeSet: " + result)
}
}
输出:
TreeSet(a, e, i, o, u)
TreeSet: a, e, i, o, u
