带有分隔符的 Scala Iterator mkString() 方法和示例
此方法与mkString()方法相同,但此处包含一个分隔符。
Method Definition: def mkString(sep: String): String
Return Type: It returns the string representation of the stated collection with a given separator.
示例 #1:
// Scala program of mkString()
// method with 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
示例 #2:
// Scala program of mkString()
// method with 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
