Display sum of consecutive numbers

Hi Guys,

I need your help on while statements.

Currently i have this:-

public class Numbers
{
public static void main(String[] args)
{
int x = Integer.parseInt(args[0]);
int y = Integer.parseInt(args[1]);

while ( x <= y)
{
System.out.println( x );
x = x + 1;
}
}
}

How do I modify the code above to include display of sum of the consecutive numbers? Thanks.

Regards,
John

Do you mean the sum of x and y?

Simply,

Code:

---

public class Numbers {
    public static void main(String[] args) {
        int from = Integer.parseInt(args[0]),
            to  = Integer.parseInt(args[1]);

        for (int i = from, total = 0; i < to; ++i)
            System.out.println(x + ": " + (total = total + x));
    }
}

The whole concept of the project is so "Given a positive integer Target, in how many different ways can Target be expressed as a sum of consecutive positive integers?"... The user inputs the number in a test box and the result is displayed in a listbox.Example of needed process:
if Target = 63, there are six solutions:
3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11
6 + 7 + 8 + 9 + 10 + 11 + 12
8 + 9 + 10 + 11 + 12 + 13
20 + 21 + 22
31 + 32
63

you need to be more explicit

Hmm... for x = x + 1; you should just use x++;. It saves time. Other than that... I'm not sure what your Q is.

if you mean you are having a serial of inputs and you want to get their sum;

after taking them from the user in an array

this is the operation:

public static sum (int[] a)
{
int sum=0;
for(int i=0;i<"array size";i++)
{
sum+=a[i];
System.out.println( sum );
}
}

its quite simple...
public class Numbers
{
public static void main(String args[])
{
int x = Integer.parseInt(args[0]);
int y = Integer.parseInt(args[1]);
int sum=0;
while (x<=y)
{
sum+=x;
++x;
}
System.out.println("Sum of the consecutive numbers within "+x +"and" +y +"is: "+sum);
}
}

@john
the above post is for the sum of all the consecutive numbers...
plss be clear..
do u want the sum of each 2 consecutive numbers or 3 consecutive numbers or...so.on..

thanks
