Java can't detect key strokes on the console.
But you could stop when the user enters an empty line.
For that you'd need to use nextLine() rather than than next(), and check for empty line read.
(That means you can never call anything but nextLine() on your Scanner. It's either nextLine() or the others. No mixing them.)

How to add the numbers to the list only by using next line??

[shut storm]

"add the numbers to the list"?

[raw sage]

String token = cons.next(); numbers.add(Integer.parseInt(token));

[shut storm]

I see

And, errm, you gave me these lines,

and you need me to tell you how to replace next() with nextLine()?

[raw sage]

yes!

[shut storm]

String token = cons.nextLine(); numbers.add(Integer.parseInt(token));

[raw sage]

No, I don't think it's that. I remade it but it still won't work:

[terse junco]

        List<Integer> numbers = new ArrayList<Integer>();
        Scanner cons = new Scanner(System.in);
        System.out.println("Insert numbers");
        while (cons.hasNext()) {
            String token = cons.next();

            try {
                numbers.add(Integer.parseInt(token));
            } catch (NumberFormatException nfe) {

            }
            if (cons.nextLine().isEmpty()) { 
                break;
            }
        }
        return numbers;
    } ```
