View Full Version : problem with nextLine() method in java...

March 10th, 2009, 12:41 AM
guys, I'm implementing this code that takes in attributes from a product, by my first scan is jumping to the next line, not giving me an opporunity to enter the name for the description and jumping straight to price....but if I use the next() method, then the string can take only one word... and I would like to enter things like "Pepsi Cola".... any help appreciated

String description = myscan.nextLine();
double price = myscan.nextDouble();
int qty = myscan.nextInt();
vm.addProduct(new Product(description, price, qty));

I really hate Scanner and I remember a thread about a month ago with an issue like this. Here is the thread (http://ubuntuforums.org/showthread.php?t=1068267) and one of the solutions was to try using this for your Scanner if you aren't already:

Scanner input = new Scanner(new BufferedReader(
new InputStreamReader(System.in)).readLine());

I used that line, but that threw an exception which made me add a "try catch"... but when run the app, nothing happens

Try this out to get the input

Scanner console = new Scanner(System.in);
String description = console.next();
String price = console.next();
double pr = Double.parseDouble(price);
String quantity = console.next();
int qty = Integer.parseInt(quantity);
