My program does work perfectly, although the task isn't being completed.

Question about the task

Adding

Java Syntax, Level 4, Lesson 16

Resolved

I've checked the program execution on Eclipse and it works perfectly. wherein have I done wrong? TY

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 buf = new BufferedReader(new InputStreamReader(System.in)); int sum =0; while (true) { int a = Integer.parseInt(buf.readLine()); sum+=a; if (a==-1) { System.out.println(sum); } } } }

You have to put the condition directly after the number input, and you must add the break command to terminate the program.

When you enter -1 the program goes back to the beginning of the while loop and asks for another int. You have to break the loop and then print your sum.
