:) First of all, this is a *servlet* interest group, so this is severely
off-topic. So please, if you reply again, reply to me personally, I'll be
happy to help you. Second, this is pretty basic java stuff that hopefully
in the future you can figure out with a java book, an interactive debugger,
and/or by putting println()s *inside* your loop.
Why is p==5 when the loop finishes? Because the "p < 5" is the while
condition. P is incremented until it equals 5, at which point the loop
finishes. The equalivalent code would be:
while (p < 5)
{
...
p++;
}
So t is 4 because the loop is executed four times (p==1...p==4), and you
increment it once per loop.
Meanwhile, you have set m to always be greater than t, and you coded it as
t++ not ++t, so that is why it always does the m = p + t line. Equivalent
code for the most inner block of code would be:
if (t > m) {
t = t + 1;
m = p + t;
}
else t = t + 1;
That is, because you said t++, if first checks to see if t > m, then it
increments t, then if t was greater than m, it does the m = p + t.
Hope this is clear,
