I have little experience using delimiters and i need to read a text file that stores several objects whose data is stored in single lines separate by commas (","). The seperate strings are then used to create a new object which is added to an arraylist.

I am using Scanner to read the file, however i get a no line found error and the entire file is stored into one string:
Scanner read = new Scanner (new File("datafile.txt"));
read.useDelimiter(",");
String title, category, runningTime, year, price;
while (read.hasNext())
{
title = read.nextLine();
category = read.nextLine();
runningTime = read.nextLine();
year = read.nextLine();
price = read.nextLine();
System.out.println(title + " " + category + " " + runningTime + " " +
year + " " + price + "\n"); // just for debugging
}
read.close();
A delimiter separates the data fields. It is usually a comma, but can also be a pipe, a tab, or any single value character. An enclosing character occurs at the beginning and the end of a value. It is sometimes called a quote character (because it is usually double quotes), but you can use another character instead.
Data in a delimited text file is arranged in rows and columns, with one entry per row. Each column is separated from the next by a field separator character. The following file snippet illustrates characteristics common to many delimited files.
Use read.next() instead of read.nextLine()
title = read.next();
category = read.next();
runningTime = read.next();
year = read.next();
price = read.next();
