Music Player

Question

You are building a Music Player app.
You need to implement the MusicPlayer class, which should hold the track names as Strings in an array. The array is already defined in the given code.
The player should support the following functions:
add: add the given argument track to the tracks array.
show: output all track names in the player on separate lines.
play: start playing the first track by outputting "Playing name" where name is the first track name.
You can add a new item to an array using +=, for example: tracks += track

Answer 1

Try this, the code is up and running
class MusicPlayer {
private var songs: Array<String> = arrayOf()
//your code goes here
fun add(track: String): Array<String>{
songs = songs + track
return songs
}
fun show(){
for(track in songs.indices){
println(songs[track])
}
}
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()
}

Answer 2

class Track:
def __init__(self, title, next):
self.title = title
self.next = next
class Player:
def __init__(self):
self.head = None
def add(self, title):
if not self.head:
self.head = Track(title, None)
return
curr = self.head
while curr.next:
curr = curr.next
curr.next = Track(title, None)
p = Player()
d = []
while True:
x = input()
if x == 'end':
break
p.add(x)
d.append(x)
for i in d:
print (i)

class MusicPlayer {
private var songs: Array<String> = arrayOf()

val m = MusicPlayer()
while(true) {
var input = readLine()!!
if(input == "stop") {
break
}
m.add(input)
}
m.show()
m.play()
}

Answer 10

Alessio Pustorino !! The :Array part after the "fun add" was what I had missed. Thank you.
Do you happen to know why it is needed?

Answer 14

All are wrong answer, Try mine
class MusicPlayer {
private var tracks: Array<String> = arrayOf()
fun add(track: String) {
//your code goes here
tracks += track
}
fun show() {
//your code goes here
for (track in tracks){
println(track)
}
}
fun play() {
//your code goes here
println("Playing ${tracks[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()
}

Answer 15

class Track:
def __init__(self, title, next):
self.title = title
self.next = next
class Player:
def __init__(self):
self.head = None
def add(self, title):
if not self.head:
self.head = Track(title, None)
return
curr = self.head
while curr.next:
curr = curr.next
curr.next = Track(title, None)
p =Player()
while True:
x =input()
if x == 'end':
break
p.add(x)
n = p.head
while n!= None:
print(n.title)
n = n.next
# it may be work
