Am having this error, unresolved reference: play, on MusicPlayer. My code below On Kotlin

class MusicPlayer { private var songs: Array<String> = arrayOf("Purple Haze","Under Pressure","Walk This Way","Playing Purple Haze","Stop") //your code goes here fun add(track: String): Unit{ songs += track } fun show(){ println("$songs[0]\n$songs[1]\n$[2]\n$songs[3]") } fun pay(){ val play = songs println("$songs[0]") } } fun main(args: Array<String>) { val m = MusicPlayer() while(true) { var input = readLine()!! if(input == "stop") { break } m.add(input) } m.show() m.play() }

Dave Enyi Did you name the function pay() in error? Did you mean to name it play()

Hi Dave Enyi I couldn't get any of your functions to work. I suggest you work on one aspect of the code at a time, comment out the other calls. Remember, you either need to return from a function, or print the result. fun add() does nothing at the moment. Also, check your types, and you may wish to use a loop in your fun show() because the tests will have a varied number of songs. Good luck

You should try this : class MusicPlayer { private var songs: Array<String> = arrayOf() //your code goes here fun add(name:String){ songs += name } fun show(){ songs.forEach(){ item -> println(item) } } fun play(){ println("Playing "+ songs[0]) } } fun main(args: Array<String>) { val m = MusicPlayer() while(true) { var input = readLine()!! if(input == "stop") { break } m.add(input) } m.show() m.play() }
