The Nineteenth Byte

By legal proofs I meant meta post

@Anastasiya-Romanova秀 Sure. I personally wait a bit to give others a chance before answering myself, but that's just what I do.

@Anastasiya-Romanova秀 if you are interested here is the relevant help center post stackoverflow.com/help/self-answer

A: Can I compete in my own challenge?

Yes, particpating in your own challenge is allowed, no matter of which challenge type. The Help Center says: It’s also OK to participate in your own puzzles. But if you participate in your own challenge, it is recommended to wait some time before posting an answer to give others a chance to...

@RohanJhunjhunwala Wrong SE site. We probably have the same text right now, but that will hopefully change in the future.

@RohanJhunjhunwala I know that fact, what I'm asking is here

I'm asking about ethical aspect

Not general rules

4:03 AM

Oh my bad, Let me delete the post

@Anastasiya-Romanova秀 it is ethical as long as you dont win

@Dennis Thanks for the relevant meta post

@Anastasiya-Romanova秀 also like Dennis mentioned do allow others time to answer

@Dennis if the implementation is run on machine with infinite memory, yes

btw quick-question: which do u think is faster to learn C++ or Java?

I know C but i also am very familiar with OO concepts

@RohanJhunjhunwala You can win too. The meta post mentions it.

Java is faster to learn

4:06 AM

But it takes more time to type. :P

@Dennis yes while you technically can win, I do try not to have myself win a challenge

C++ is literally 100 times more complicated than Java.

@EᴀsᴛᴇʀʟʏIʀᴋ nice drawing although I disagree with the image

Java is fun come to the dark side

And learn lots of reflection (although C probably has it too)

@feersum I'm familiar with C so with that, isn't Java more complicated with all of its interface, class, public static main void?

4:07 AM

@Downgoat Um, sure.

@Downgoat an I borrow your machine with infinite memory, thanks! I only need it for a day or two

do u need to import System in Java? tutorial isn't showing it but I've swear I've seen it done before

Well, if you had to pass a test 'Write C++ code that does X', you could pass it with C.

@Downgoat it's fairly sinple.

@Downgoat do't rely on code golf code for best practices

import System is not needed

But if you had to know the rules of the language, C++ is much more.

4:08 AM

@RohanJhunjhunwala I guessed so but is it good practice?

But it can golf off bytes with System.out.println -> out.println() , I would say its generally not

ok

import System is un idiomatic as far as I can tell

I agree, no one does that in normal code.

question: what is java equivilent of header file?

4:09 AM

whoops

meant to edit

package

package somepackage;

does java have named properties?

@Downgoat Java

@Downgoat What does that mean?

@Downgoat Nothing

does java have loose-typed mode?

4:10 AM

idk, what named properties are

@Downgoat type inference

@Downgoat Basically automatic headers

@Dennis Right now I have no ability to create a programming language and it's unlikely in the future, so I'm wondering can I create my own 'built-ins' as a function or routine for competing in golf-code but the so-called built-ins is excluded from bytes count?

@RohanJhunjhunwala it has that? awesome

@Downgoat No, not even type inference (i.e. var)

ArrayList<Type> a = new ArrayList<>();

4:10 AM

Hi guys

@ASCII-only see the above comment

@RohanJhunjhunwala That's the only "loose typing" in java

yes

Rarely used anyway

eh... I use it, solely cause netbeans recommends it

4:11 AM

Oh. So to understand: I can simple add files to a "package" and they all share their classes?

that's very nice

@Downgoat ?

@Downgoat that is correct

I'm putting together a healthbar renderer program (for a forum game I plan on starting soon), and this is what I have so far:

import java.awt.*;
import java.awt.image.*;
import java.io.File;
import java.io.IOException;
import java.util.*;

import javax.imageio.ImageIO;

public class BossHealthBar {
	public static void main(String[]arg) throws IOException{
		BufferedImage bi=new BufferedImage(2000,60,BufferedImage.TYPE_INT_ARGB);
		Scanner s=new Scanner(System.in);
		int hp=s.nextInt();
		int mhp=s.nextInt();
		int barsTotal=0;
		int barsLit=0;
		while(mhp>200){
			barsTotal++;
			mhp-=200;
		}
		while(hp>200){
			barsLit++;

@Downgoat Yes, use package <name>; at the top

@ASCII-only e.g. new Goat(breed: "sheep")

4:12 AM

@SuperJedi224 this is not code review

Mitch Schwartz

@Dennis i don't know a lot about this, but you may be interested (probably not) in shinh's bflisp github.com/shinh/bflisp

@Downgoat Goat upGoat = new Goat(Breeds.sheep);

where upGoat is the name of the new goat

@RohanJhunjhunwala oh so java has enums?

yes

4:13 AM

brb googling >_>

@Downgoat No

@ASCII-only yes

> "Multiple users are discussing PHP" --> "ignore them"

Hahaha

enum x{

C# is a lot better than Java in most things

4:13 AM

enum stuff{
}

@RohanJhunjhunwala That's not true named params

@Anastasiya-Romanova秀 By our rules, you'd still have to create a language. That doesn't have to be complicated though; the interpreter could simply define a set of function and eval the source code.

@ASCII-only Ease of programming is not one of them

@SuperJedi224 It is

@ASCII-only ?

4:13 AM

@ASCII-only I'd like to learn C++ or C# but i only have 1 hour....

Though frankly java's not great there either

@Downgoat C#, you get to use var

@Downgoat learn java come to the dark side

Code once run everwhere

@SuperJedi224 How

@RohanJhunjhunwala Same with C# + Mono

@ASCII-only shhhhh

Java is the language of the future

4:15 AM

@ASCII-only yes but i spent like 5 minutes and i know so much java

yes, I finally have gotten someone to join forces

Soon you'll be ~~golfing~~ bowling answers in java

With Geobits and I

@MitchSchwartz A C compiler in brainfuck? Oh dear...

C# has named and optional params

@Downgoat C# is more similar to JS, you'll learn C# faster

A C compiler in brainf*** which compiles C to BF is even more wizardry

> This file is too big to show. Sorry!

Quill

4:16 AM

@EᴀsᴛᴇʀʟʏIʀᴋ pls open an issue

@Downgoat java is superior

Quill

@EᴀsᴛᴇʀʟʏIʀᴋ pls open an issue

@ASCII-only are you kidding 50% of JavaScript is Java

i am also on mac so can't c# iirc

;_;

@RohanJhunjhunwala yes i agree now

@Dennis So it means I cannot create my custom built-ins for golfing here, right?

owow java has like same prop names as JS

4:17 AM

@Downgoat C# is basically a clone of Java with JS features that can be managed

@Downgoat Mono

@ASCII-only i will learn c# later maybe

@Downgoat C# is mostly the same, but they start with capitals

C# isn't option anyway

@Downgoat :D

@ASCII-only :D PascalCase FTW

4:18 AM

@Anastasiya-Romanova秀 No, you can, but you just have to call it a language.

@Anastasiya-Romanova秀 Sort of. You need an interpreter or at least a transpiler, and once you do, you pretty much created a new language.

@Downgoat seriously no var, no optional params and no named params is such a pain for larger projects

That's really all that V is

@ASCII-only i just need to know enough java for copmuter science teacher to know im legit

4:19 AM

I guess I made the image output too wide

@RohanJhunjhunwala google is giving me long answers. can you quickly tell me what different between String[] and ArrayList<String> is?

@Anastasiya-Romanova秀 What language are you planning on adding builtins to?

@Downgoat ArrayList allows you to add elements to the end

@Downgoat String[] is fixed-length, ArrayList<String> is not

4:21 AM

It is a dynamically resizing array

@Downgoat I guess it's good to learn though, I'm using it because Java is probably faster on Android

@Downgoat Basically ArrayList has add, remove, get and put

whole world also uses java

@RohanJhunjhunwala ah ok

how to convert array to arraylist?

Arrays.asList(someArray) @Downgoat (I think

or manually

Arrays?

ArrayList x = new ArrayList(); for(String s:array)x.add(s);

@Downgoat so static methods

Arrays is a static method library

oh my bad

clueless without netbeas d'oh

4:23 AM

no wait

@RohanJhunjhunwala what does :array do?

@RohanJhunjhunwala my bad, it is Arrays

@Downgoat in

ah ok

@Downgoat enhanced for loop

foreach(var s in array) basically

4:24 AM

^^

java is cool

@DJMcMayhem Well, by custom built-ins I meant functions that I can be used in the future for golfing but it must store in a repository here. Don't know how to use Github but we can use a sanbox on meta post

Eamon Olive

@Downgoat since no one else is, let me advocate C++. It took me a week to learn C++ while I have spent the last month and a half unsuccessfully trying to understand java. Not the case for everyone but C++ can be very easy to learn especially if you are familiar with C.

brb reprogramming cheddar in java

for(Type t:array) is for each t of Type t in the array

4:24 AM

Also I fiddled with the code for deciding the width of the output image, should work better now

I have converted Downgoat my life acheivement

Yeah, that's fine

@SuperJedi224 D: pointing to C#

It shows 12/24 BTW

@ASCII-only Now it's pointing at the post I meant it to point at

@EamonOlive C++ is definetly on my TODO list for languages to learn but while I'm familiar with C, I'm not an expert and considering my experise at JavaScript, I feel Java will be quicker to learn for me than C++

@RohanJhunjhunwala :D

4:26 AM

I kinda know C++, but not very well

:D

@EamonOlive Yeah, but Downgoat is more familiar with OOP JS

@RohanJhunjhunwala ok if java regex doesn't have lookbehind I'm leaving

@Anastasiya-Romanova秀 What language were you planning on writing them in though?

:O :O :O :O

4:27 AM

@Downgoat No D: why

JAVA DOESNT HAVE REGEX LITERAL

OMG THIS IS DEAL BREAKING

Also, I highly recommend github, you should learn it

@Downgoat Use .NET regex, it's the most powerful

@Downgoat relax String.replaceAll();

hm but the regex flavor looks good

4:27 AM

@DJMcMayhem Doesn't exist yet

@ASCII-only ik

got to sleep now rip

gn

@RohanJhunjhunwala bai

@DJMcMayhem link

i gtg sleep too

4:27 AM

@Downgoat bai

bai

@Dennis @DJMcMayhem Let say I want to compete in golf-code using VBA that involves alphabet, but it turns out VBA has no built-in alphabet. So I create a function say A()="ABCDEFGHIJKLMNOPQRSTUVWXYZ" in meta sandbox then I can use that function in the future

@Anastasiya-Romanova秀 You can just assign to a variable to make it shorter

@ASCII-only I did, but it's 30 bytes

@Downgoat It is rather annoying

4:29 AM

@Anastasiya-Romanova秀 Oh yeah

@RohanJhunjhunwala PLS HALP HOW TO CHANGE STRING IN JAVA

If I can call function A, then it's a byte

@Downgoat Change?

strings in java are immutable

@Anastasiya-Romanova秀 The best way to do that would be make a VBA library, and put it somewhere online, then add import my_lib to any submissions using it

4:29 AM

everything is pass by vlaue too ;_;

idk how to anything anymore

@Downgoat How do you want to change string?

e.g.

@Downgoat Yeah, same as JS

Or whatever the syntax is

String a = "hai"
a = a+ " goat"

SO is telling me I can't do that

4:30 AM

wat

@ASCII-only wait sorry see again

A: Change string in Java

Your method cannot work with the current interface because of two reasons: Strings are immutable. Once you have created a string you cannot later change that string object. Java uses pass-by-value, not pass-by-reference. When you assign a new value to s in your method it only modifies the local...

@DJMcMayhem I wish I had that kind of ability but I couldn't. I'm still pretty new to code in general

I mostly use it for reporting purposes

@Downgoat You can, just not in a method

@Downgoat That's exactly backward. Everything in Java is pass by reference (Objects), except non-array primitive types.

wait wat

4:31 AM

Well, I did use it to evaluate Integral too in the past

@Downgoat Use semicolons

@Downgoat If you change in a method, it creates a new instance, so it won't change the variable passed in

@ASCII-only wait so is Java pass-by-reference like JS's?

I can pass a class and it won't copy it?

@Downgoat Yes

@SuperJedi224 oh sorry

@ASCII-only @internet Y U LIE TO GAOT ;_;

4:32 AM

Also, I drew this on Drawception a few days ago:

@Downgoat It's just you can't reassign a parameter in a method since it's pass by reference

Unfortunately java doesn't let you mark arguments as variable references, though JS really doesn't either

@Downgoat hmm .NET has no regex literal either

Anyway, I guess I need to go now

5:54 AM

Hey @LeakyNun. I think I found the bug in my Bernoulli code, but I have another question for you

@Sherlock9 go ahead

Sherlock9

You found an Actually program that would add fractions even with other stuff on the stack. Say you have a list of several fractions. How would you sum them?

@Sherlock9 find the product of the denominators

scale up each fraction

integer addition (sum)

then attach the product as denominator

then use the simplifier

Sherlock9

Thanks a bunch :D I'll write it up as soon as I get home
