Reaaaallly Need Help With My Array Code! Any Takers? ;D
This probably looks terrible, but it's my first experience with Java this year ;P. Everything works fine now except for the fact that when I run the program the values for Song#, songRating, and numberOfSongs all come out as 0. It's aggrevating. I know, I suck at this. I will gladly return a favor to anyone who can either give me some pointers or help me fix this before I cry lol. Thanks :)
import java.util.Scanner;
public class PlayListBuilderArray
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
String inputText;
int numberOfSongs = 0;
do {
System.out.print("How many songs would you like to add to the playlist? (Can only add up to 15) : ");
inputText = in.nextLine();
numberOfSongs = Integer.parseInt(inputText);
if (numberOfSongs < 1)
{
System.out.println("ERROR - You can't enter "+numberOfSongs+" songs.");
}
else if (numberOfSongs > 15)
{
System.out.println("ERROR - Please enter 15 songs or less.");
numberOfSongs = 0;
}
} while (numberOfSongs < 1);
PlayList[] songList = new PlayList[numberOfSongs];
for (int count = 0; count < songList.length; count++)
{
songList[count] = new PlayList();
System.out.print("What is song #"+(count+1)+"\'s title? ");
inputText = in.nextLine();
songList[count].setSongTitle(inputText);
System.out.print("Who is song #"+(count+1)+" written by? ");
inputText = in.nextLine();
songList[count].setArtistName(inputText);
System.out.print("What is song #"+(count+1)+"\'s album titled? ");
inputText = in.nextLine();
songList[count].setAlbumTitle(inputText);
System.out.print("What is song #"+(count+1)+"\'s rating? ");
inputText = in.nextLine();
}
ArrayObjectTools.printArray(songList);
for (int count = 0; count < songList.length; count++)
{
System.out.println("Song #"+(count)+":");
System.out.println(songList[count]);
System.out.println("-----------------------------------------");
}
}
}
Result of running the program if I chose only 1 song:
-----------------------------------------
Song #0:
Artist Name: wanda
Song Title: jade
Album Title: portia
Song Rating(stars): 0
Number of Songs in Playlist: 0
-----------------------------------------
Begging of Code Source. With gets and sets.
Ignore the commenting on this. I was using my last one to save a little time and will edit it later.
