Having issues with this task

Question about the task

Resolved

I can make this code "work" but not verify. The verification says to make sure it calculates everything properly. I have tried many different versions of this task and I am not getting what I am missing. Any help would be appreciated. Thank You.

Use the keyboard to enter numbers.
If the user enters -1, display the sum of all entered numbers and end the program.
-1 should be included in the sum.

Hint: one of the solutions to this problem uses the following construct:

while (true) {
    int number = read the number;
    if (check whether the number is -1)
        break;
}

Requirements:

The program should read the numbers from the keyboard.
If the user enters -1, the program should display the sum of all entered numbers and then end.
The program must calculate and display the sum of the entered numbers.
The program must use a for loop or a while loop.

package com.codegym.task.task04.task0442; /* Adding */ import java.io.*; public class Solution { public static void main(String[] args) throws Exception { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); int a = Integer.parseInt(reader.readLine()); int sum = 0; while(sum == 0) { // this line here int b = Integer.parseInt(reader.readLine()); sum = a + b; if(a == -1) { System.out.println(sum); // this line here...?? break; } System.out.println(sum); } } }

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

you are instructed to break the loop only when the input is -1, other than that, the loop should continue taking inputs, the errors I could find were: 1. you should change the loop terminating condition on line 17, once you have added two distinct numbers to sum inside the loop, the next time the loop starts, sum will always be a non-zero value, so the loop will not run the second time. 2. In line 19, the program will keep adding the variable 'a' to sum in every loop, so basically the sum will always contain 'a+b' 3. sum should be displayed only once at the end, but here, in every iteration of the loop, sum will be displayed.
