doubt

[lp]

i came across this question in JQ++. it is as follows:
public class Test
{
public static void main(String[] args)
{
int sum=0;
for(int i=0,j=10;sum>20;++i,--j)
{
sum +=i+j;
}
System.out.println(sum);
}
}
i thought the answer would be 20 but instead when i saw the answer it was 0.could anyone please explain this .
Thanks
Lakshmi

The for loop never executes because the test condition (sum > 20) fails on the first pass.

You are getting 0 as the output because the condition sum>20 is false & the program jumps out of the for loop printing sum as 0.
Change the condition to sum<=20.<br />
