I've got a bit of a problem with my java code. I am trying to create an object array that allows a line of input from a text file.
This is my code:
code withheld, solution found
That obviously initialises an object array with the size returned from the method.
I try to make a loop that reads each line from the file 'songFile' but returns an error.
Here is my code for the loop:
code withheld, solution found
This is the code for the getLineAmt method:
code withheld, solution found
Your getLineAmt(Scanner songFile) method is consuming your file when counting the number of lines. Once the method returns, your Scanner has arleady read the file and as reached the end.
One way to solve that is to simply use a List object instead of an array, so that you do not need to know the size or your file in advance.
List<Song> songList = new ArrayList<Song>();
while(songFile.hasNextLine()) {
songList.add(new Song(songFile.nextLine()));
}
You are getting this error because you are trying to read a line without making sure if there are any more lines to be read. You need to modify and add the following check before reading the nextLine
for (int i = 0; i < songArray.length; i++)
{
if(songFile.hasNext()){
songArray[i] = new Song(songFile.nextLine());
}
}
You're counting the lines in the song file, so you are at end of stream, so when you call nextLine() there isn't one. Use an ArrayList<Song> instead of an array of Song[], then you don't need to count the lines at all.
