Scala Iterator mkString() 方法,带有开始、分隔符和结束示例
此方法也与mkString()方法相同,但这里它带有一个开始、一个分隔符和一个结束。
Method Definition: def mkString(start: String, sep: String, end: String): String
Where, start is the starting string, sep is the separator string and end is the ending string.
Return Type: It returns the string representation of the stated collection along with a start, a separator and an end.
示例 #1:
// Scala program of mkString()
// method with a start, end
// and a separator
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating an Iterator
val iter = Iterator(1, 2, 3, 5)
// Applying mkString method
val result = iter.mkString("*", "0", "*")
// Displays output
println(result)
}
}
输出:
*1020305*
其中, start 是* , sep 是0 , end 也是* 。
示例 #2:
// Scala program of mkString()
// method with a start, end
// and a separator
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating an Iterator
val iter = Iterator(1, 2, 3, 5)
// Applying mkString method
val result = iter.mkString("#", "*", "#")
// Displays output
println(result)
}
}
输出:
#1*2*3*5#
