Answer 1

You can use additional property in Movie class to convert list to string, e.g. val genre:

data class Movie(
        @SerializedName("movie_name")
        val movieName: String,
        @SerializedName("genres")
        val movieGenre: List<String>
) {
    val genre: String
        get() = buildString { // builds new string using append() method on each item of movieGenre
            movieGenre.forEach { append(it) }
        }

}

Here is how to access it:

val movie: Movie = getMoviewFromInternet()
val movieGenre: String = movie.genre
