toString() 方法是用来返回TreeSet对象的字符串表示。
方法定义: def toString():String
返回类型。它返回TreeSet对象的字符串表示。
例子 #1:
// Scala program of toString()
// 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 toString method
val result = t1.toString
// Display output
print("String representation of the TreeSet object: " + result)
}
}
输出。
TreeSet(1, 2, 3, 4, 5, 6)
String representation of the TreeSet object: TreeSet(1, 2, 3, 4, 5, 6)
例子#2。
// Scala program of toString()
// 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 toString method
val result = t1.toString
// Display output
print("String representation of the TreeSet object: " + result)
}
}
输出。
TreeSet(a, e, i, o, u)
String representation of the TreeSet object: TreeSet(a, e, i, o, u)
