While loop calculating the sum of all numbers from 1 - 1000

[hanslo91]

public class Main
{
    public static void main(String[] args)
    {
        int sum = 0;
        while (sum <=1000)
        {
                System.out.println(sum);
                sum++;
        }
 
 
    }

} am stuck here I have tried using a seperate interger but I cant seem to figure this out! Please help.

Define a new integer like you have defined "sum", but call it "counter". Set it to start value 1 before entering the while loop. Inside the while loop, increase it by one.
Run the while loop as long as this counter is lesser or equal 1000 (condition after "while").
Also, inside the while loop, take the old value of "sum" and add the value of the counter to it.

am trying my best I am working within a leanring app and it keeps telling me I have the incorrect result. The new program that I put in after reading your comment is,

public class Main
{
    public static void main(String[] args)
    {
        int sum = 0;
        int i = 1;
 
        while (i <=1000)
        { 
 
                System.out.println(sum);
                i++;
                sum = sum + i;
        }
 
 
    }
}

Please use code tags when posting code or formatted data.

You need to flip lines 12 and 13, otherwise you're skipping number 1.

Ok thanks Rabbit! I see that error now which I consitantly overlooked. I switched those two lines but now im having the issue where it isnt adding to what it should which is 500500.

public class Main
{
    public static void main(String[] args)
    {
        int sum = 0;
        int i = 1;
 
        while (i <=1000)
        { 
 
                System.out.println(sum);
 
                sum = sum + i;
                i++;
        }
 
 
    }
}

Im sorry for asking so many questions but im not taking an actual class. If it is something really simple im missing please tell me its simple but dont tell me the code. I think im gonna review loops.

The printout should be after line 13, otherwise you're printing out the value before the numbers are added.

Oh man I can't believe it! Thank you Rabbit, it worked and I can move onto the next course finally! Thanks again!
