Problem with printing circles

[scrum]

int width = getWidth();
int height = getHeight();

int counter = 0;
int counter2 = 0;




while (counter < 7)
{
g.drawOval(width*counter/8 ,0, width*(counter+1)/8 ,height/8);

counter++;
}



I'm trying to print a row if 8 cirlces the same size along the top of a jpane, but it doesn't work.

the first circle prints
the second circles starts at the right place but streches out to double where it should be


the third also starts at the right place but stretches out weird again.

can you show a screenshot?

You're forgetting your basic arithmetic :) Division is applied before subtraction, so you're doing width * (counter / 8) which is always zero (counter being an int). You want (width * counter) / 8. Also, here you have an initialiser, a test, and an incrementor, which is what for loops are for, although to optimise we can put the incrementation and the addition steps together:
int width = getWidth(), height = getHeight();

for(int i = 0; i < 8; )
g.drawOval((width * i) / 8, 0, (width * (++i)) / 8, height / 8);Also note that because you started from zero, if you want to execute the loop eight times you must loop until i < 8 or i <= 7. i < 7 will only execute seven times.

This kind of forums are really helpful for those who are working on java.
It is a very informative site.
