"Read the items from the text file(use tokenizer), creates the approapriate class instance of each item and stores them in an arraylist whose data type is renatl item."
This is my code so far, do not know how to add it to the arraylist
public static void main(String[] args) {
ArrayList<RentalItem> ri = new ArrayList<RentalItem>();
String filename;
String data;
Scanner kb = new Scanner(System.in);
System.out.print("Enter File Name: ");
filename = kb.nextLine();
try {
File inFile = new File(filename);
Scanner inputFile = new Scanner(inFile);
while (inputFile.hasNext()) {
data = inputFile.nextLine();
System.out.println(data);
StringTokenizer tokens = new StringTokenizer(data, ";");
String title = tokens.nextToken();
int year = Integer.parseInt(tokens.nextToken());
int upc = Integer.parseInt(tokens.nextToken());
int stock = Integer.parseInt(tokens.nextToken());
String platform = tokens.nextToken();
String movietype = tokens.nextToken();
}
inputFile.close();
} catch (FileNotFoundException fileError) {
System.out.println(filename + " cannot be found!");
} catch (NoSuchElementException dataError) {
System.out.println("Error reading file!");
}
}
}
