Hi I am trying to make this code work, but when I input myname3 this it what it gives me, although I am asking for the length it doesn't give but the width is some
and the length is -1

you didn't need to close the previous thread tbh

torn jewel May 25, 2023, 3:16 PM

#

I added the if statement here aswell

torn jewel May 25, 2023, 3:16 PM

#

idle rover you didn't need to close the previous thread tbh

yes i did

idle rover May 25, 2023, 3:16 PM

#

you didn't

torn jewel May 25, 2023, 3:17 PM

#

idle rover May 25, 2023, 3:17 PM

#

again, you didn't

torn jewel May 25, 2023, 3:17 PM

it's closed man

idle rover May 25, 2023, 3:17 PM

#

if you're trying to get an integer, why not just use parseInt

idle rover May 25, 2023, 3:18 PM

#

torn jewel it's closed man

...ok? im saying you didn't need to close it, you couldve just used that thread

idle rover May 25, 2023, 3:18 PM

#

idle rover if you're trying to get an integer, why not just use `parseInt`

and use hasNextInt or catch the error

#

you can't get non-integers with the replace you have anyways, since the . gets removed

#

i don't think it'd make much sense to input 3.0 and get back 30

torn jewel May 25, 2023, 3:18 PM

#

No I get 3.0

idle rover May 25, 2023, 3:19 PM

#

you don't

torn jewel May 25, 2023, 3:19 PM

#

when I had the length%0 == 0

#

It somehow worked but it reset me

#

let me show you

idle rover May 25, 2023, 3:19 PM

#

torn jewel It somehow worked but it reset me

it doesn't

torn jewel May 25, 2023, 3:19 PM

#

#

idle rover May 25, 2023, 3:19 PM

#

% does division. you can't do % 0

torn jewel May 25, 2023, 3:19 PM

#

look man

#

this is what it does for me

idle rover May 25, 2023, 3:19 PM

#

that's not what i said

#

im saying if you input 3.0, you get 30

#

do you want integers only or not

torn jewel May 25, 2023, 3:20 PM

#

let me explain why i am doing this

idle rover May 25, 2023, 3:20 PM

#

no, don't

#

do you want integers only or not

torn jewel May 25, 2023, 3:20 PM

#

ok

#

yes integers only

idle rover May 25, 2023, 3:21 PM

#

then use parseInt/hasNextInt/nextInt instead of all your double stuff

#

if you want integers, then use the integers

torn jewel May 25, 2023, 3:21 PM

#

ok

#

one last thing

idle rover May 25, 2023, 3:21 PM

#

don't attempt to fix the given value, just treat it as is and if it doesn't work then it doesn't work and prompt the user again

torn jewel May 25, 2023, 3:21 PM

#

why does my program work when I say length%0 == 0

idle rover May 25, 2023, 3:21 PM

#

torn jewel why does my program work when I say length%0 == 0

it doesn't, and you aren't

#

you're doing % 1

#

oh huh you are

torn jewel May 25, 2023, 3:22 PM

#

idle rover May 25, 2023, 3:22 PM

#

didn't read the entire thing

torn jewel May 25, 2023, 3:22 PM

#

only when I say %0 it works

idle rover May 25, 2023, 3:22 PM

#

that's because you're short-circuiting and it never actually evaluates teh % 0

torn jewel May 25, 2023, 3:22 PM

#

when I put %1 it doesn't

idle rover May 25, 2023, 3:22 PM

#

torn jewel only when I say %0 it works

it does not

#

/run

System.out.println(1 % 0);

urban needleBOT May 25, 2023, 3:22 PM

#

@idle rover I only received java(15.0.2) error output

Exception in thread "main" java.lang.ArithmeticException: / by zero
	at temp.main(file0.code.java:2)

torn jewel May 25, 2023, 3:23 PM

#

ok so why doesn't it work when I put %1

#

idle rover May 25, 2023, 3:23 PM

#

oh right you're using doubles

#

/run

System.out.println(1d % 0);

urban needleBOT May 25, 2023, 3:23 PM

#

Here is your java(15.0.2) output @idle rover

NaN

idle rover May 25, 2023, 3:23 PM

#

torn jewel ok so why doesn't it work when I put %1

because you have a ton of issues

#

and you stumbled upon a combination of issues that looks like it works but actually fails horribly

torn jewel May 25, 2023, 3:24 PM

#

but the system output is 3

idle rover May 25, 2023, 3:24 PM

#

yeah sure

#

please stop

#

if you think you know that your program works, then why are you asking here

torn jewel May 25, 2023, 3:25 PM

#

I don't know

#

I didn't say that you don't know

#

I simply stated what I saw

idle rover May 25, 2023, 3:25 PM

#

you keep denying what im stating

idle rover May 25, 2023, 3:25 PM

#

torn jewel I simply stated what I saw

you.. didn't really see it

#

you only saw the output

#

int n = input.nextInt();
System.out.println(1);
```this program finds the factorial of `n`, i tested it with `0` and `1`

torn jewel May 25, 2023, 3:26 PM

#

Yea

#

I found the solution

#

I just had to put || instead of &&

idle rover May 25, 2023, 3:27 PM

#

there's not the solution, again, you have multiple issues

idle rover May 25, 2023, 3:27 PM

#

torn jewel I just had to put || instead of &&

nope that's not the fix, the fix is rewriting it to actually do what you want it to do

torn jewel May 25, 2023, 3:28 PM

#

I just wanted to see why %0 worked and %1 didn't and I got my answer length%1 is already = because I defined length = -1

idle rover May 25, 2023, 3:28 PM

#

look man if you're here to ask for help and then promptly ignore and deny and argue against everything the helpers try to tell you, this isn't the place for it

idle rover May 25, 2023, 3:28 PM

#

torn jewel I just wanted to see why %0 worked and %1 didn't and I got my answer length%1 is...

% 0 doesn't work. your code is too obscured for it to have an effect.

torn jewel May 25, 2023, 3:28 PM

#

I asked 2 questions you gave me the answer to the first one and I thank you for that

you've ignored it lmao

torn jewel May 25, 2023, 3:29 PM

#

no

idle rover May 25, 2023, 3:29 PM

#

you have

#

aaaand you're doing it again

torn jewel May 25, 2023, 3:29 PM

#

torn jewel one last thing

.

idle rover May 25, 2023, 3:29 PM

#

aight you have fun in your echo chamber

torn jewel May 25, 2023, 3:29 PM

#

I accepted what you said by saying ok

#

I just wanted to know why when I placed %0 it kinda worked

idle rover May 25, 2023, 3:30 PM

#

again, it doesn't

torn jewel May 25, 2023, 3:30 PM

#

And I got my answer %0 is NaN so that means it's !(%0==0), and when I placed !(%1==0) it didn't work because -1%1==0 so the while didn't work

idle rover May 25, 2023, 3:30 PM

#

% 1 is useless anyways, you always replace shit to be integers

#

completely invalidating the parseDouble you use

idle rover May 25, 2023, 3:31 PM

#

torn jewel And I got my answer %0 is NaN so that means it's !(%0==0), and when I placed !(%...

dude. % 0 is a bigger issue than % 1. % 0 works less than % 1

torn jewel May 25, 2023, 3:31 PM

#

idle rover `% 1` is useless anyways, you always replace shit to be integers

You are right but I wanted to understand the logic behind it not only the solution

idle rover May 25, 2023, 3:31 PM

#

there's no logic

#

you discovered floating-point division

#

and you again did not find the solution

#

fuck this im not paid to argue with arrogance

torn jewel May 25, 2023, 3:32 PM

#

I didn't display arrogance

#

I didn't say that you are wrong

#

simply that I've seen another issue

idle rover May 25, 2023, 3:32 PM

#

you did lmao

#

stfu

torn jewel May 25, 2023, 3:33 PM

#

I even thanked you with that previous one

idle rover May 25, 2023, 3:33 PM

#

doesn't make you any better

torn jewel May 25, 2023, 3:33 PM

#

But what I said was of a different nature

#

Even if I did your solution it still wouldn't work

idle rover May 25, 2023, 3:33 PM

#

lmao no

torn jewel May 25, 2023, 3:33 PM

#

Because instead of puting ||

#

I placed &&

idle rover May 25, 2023, 3:33 PM

#

my solution is to rewrite it because your code is a mess

#

that is not a solution

#

see what i mean about arrogance?

#

ive told you this twice already

torn jewel May 25, 2023, 3:34 PM

#

That I said that I had 2 problems

#

and once you said to use parseint hasnextint and nextint

#

I said that it's ok

#

then I just simply asked why %0 worked

idle rover May 25, 2023, 3:35 PM

#

and i said that it didn't, and i showed why. and here you are still saying that % 0 worked

torn jewel May 25, 2023, 3:35 PM

#

I said my question

#

I understood now why it worked but didn't at the same time

#

ok man I don't waant to argue anymore

#

thanks again for the help

tall heathBOT May 25, 2023, 3:36 PM
