Please help !

here is an optimal solution:

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        int number = 0;
        int total = 0;
        while(number != -1){
            number = Integer.parseInt(reader.readLine());
            total += number;
        }
        System.out.print(total);

Let me know if you have questions

while (true) { int number = Integer.parseInt(br.readLine()); if (number != -1) { sum += number; } else { sum += number; break; } } System.out.println(sum);
