Problem Definition: How to join an iterable of string in Scala?

Problem Description: We will see the method to combine Scala string iterable in Scala.

string = Array("scala", "programming", "language")

Output:

Scala programming language

Here, we need to merge all the elements of the given iterable and store the result in a string separated by some separator (in this case it is space).

You need to create an iterator over the collection to get the values.

Program:

object MyClass {
    def main(args: Array[String]) {
        val it = List("scala", "programming", "language")
        var joinString = it.mkString(" ")
        println("The joined string: " + joinString)
    }
}

Output:

The joined string: scala programming language

Reference: Scala program to convert Array to string

Here, we have created a list with string elements and then mkString to join the list of strings. Then printed the value using println method.
