Explanation

In the above program, we created a module Module1 that contains the Main() function. The Main() function is the entry point for the program.

In the Main() function, we created a string array that contains some string elements. Here, we concatenated all string array elements and join each string element with a specified separator using Join() method of String class and print the concatenated string on the console screen.
