Run it and see for yourself.If you can't do that, the work through it in your head or on paper and state what you think it is and how you got there.Don't just ask for answers without putting in any effort yourself.

i came up with 45 by adding the 2 + 1-7 then added the 3 to get 45

Do you know what this means? forgetIt = foregetIt + 3;

The answer is actually 18!!!!

Well you guys asked for the answer and i'm just trying to give it. If he wrote the syntax correctly the answer would come out to be 18, am i wrong?if so please explain what i did wrong.

Whether 18 is the correct result or not is irrelevant. Telling the OP what the result is does not help. Helping him to understand how Java works so he can figure it out on his own does help.

If you're going to just give him the answer (which I think is a bad idea), at least explain why that's the answer.

Cool i got u. Next time i will let them figure it out, but the reason i posted is because some people were telling him 45 was the correct answer and i did not see how you guys were getting that.

Thanks anyway..

I see.

The OP is actually the one who thought 45 was the answer. The other numerical answers that were given were obviously (I thought, anyway) jokes.

Would like us to wrap our responses in <sarcasm> tags in the future?

if there were no compilation error, it would be this:

int forgetIt = 0

for (i = 2; i <= 7; i++)

forgetIt = forgetIt+ 3;

System.out.println(forgetIt);

after 1st loop: i = 3, forgetIt = 3;

after 2nd loop: i = 4, forgetIt = 6;

after 3rd loop: i = 5, forgetIt = 9;

after 4th loop: i = 6, forgetIt = 12;

after 5th loop: i = 7, forgetIt = 15;

after 6th loop: i = 8, forgetIt = 18;

yay.....

man it will bring to you a nice compilation error.
