此方法與mkString()相同,但此處還添加了開始,分隔符和結束。
函數定義: defmkString(start:String, sep:String, end:String):String
返回類型: It returns the elements of the map as a string along with a stated start, separator and an end.
範例1:
// Scala program of mkString() method
// with a start, a separator and an
// end
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating map
val m1 = Map("geeks" -> 5, "for" -> 3, "cs" -> 2)
// Applying mkString method
val result = m1.mkString(">>>", "|", "--")
// Displays output
println(result)
}
}
輸出:
>>>geeks -> 5|for -> 3|cs -> 2--
範例2:
// Scala program of mkString() method
// with a start, a separator and an
// end
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating map
val m1 = Map("geeks" -> 5, "for" -> 3, "for" -> 3)
// Applying mkString method
val result = m1.mkString(">>>", "|", "--")
// Displays output
println(result)
}
}
輸出:
>>>geeks -> 5|for -> 3--
