Merging a List of Strings in Scala
To merge a list of strings in Scala, you can use the mkString
method. This method concatenates all the elements of the list into a single string, with an optional separator between each element.
Here's an example of how to merge a list of strings in Scala:
val list = List("Hello", "World", "!")
val mergedString = list.mkString
// Output: HelloWorld!
By default, the mkString
method concatenates the elements without any separator. However, you can specify a separator by passing it as an argument to the mkString
method. For example:
val list = List("Hello", "World", "!")
val mergedString = list.mkString(" ")
// Output: Hello World !
In the above example, the space character " "
is used as the separator between the elements.
That's it! You can use the mkString
method to merge a list of strings in Scala.
