Thread: Cumulative sum of entries

I need a little help.

Not sure where to go from here.

public static void main(String[] args)
    {
        Scanner keyboard = new Scanner (System.in);
 
        int value;
        int total;
 
        do
        {
            System.out.print("Enter some numbers: ");
            value = keyboard.nextInt();
 
 
 
 
            System.out.println("\nYou entered numbers " + value + ".\n");
 
 
        }
        while ( value != 0 );
    }

After each entry, the program reports the cumulative sum of the entries to date. The program terminates when the user enters a zero. If your program received as data, the values 2, 7, 3 and 0, your program should display 2, 9 and 12. Be sure to label your input and your output in an appropriate manner.

How would you do this by hand, without a computer? If somebody tells you a list of numbers, how would you keep adding them up? Write out instructions in English, that you could give to your dumbest friend, and you'll have an algorithm that should be pretty easy to translate to code.

I'm not sure what you mean by simpler, and I'm not convinced that code does what your example says it does.

That's what I would expect your output to be. If you want to print them out on the same line, you're going to have to save them to an array or a String and wait until after the loop to print them.

Good for you. What do you want us to do about it?

You may want to have a look in ArrayList, which can be found here:

ArrayList (Java Platform SE 6)

Can't use arrays. Even if we were I wouldn't know how. I am in an intro class. I only know to a certain point.

Can I ask why you didn't think my code produced what it should.

um, if you would have read the thread you would have known the question. You don't have to answer it or provide help but don't post useless stuff on a thread.

How can I be spoon feeding? It is my thread...I am just asking for help, no one has to give me any advice or help at all.

I don't want it done for me. Just need help sometimes.
