Make the simplest code unreadable

Miscellaneous Topics
#1

Just for fun I made a simple code, as unreadable as possible.

The result:

    public static void main(String[] args) {
        String txt = "";
        for(int i=0; i<6; i++){txt += txt .length() == 0 ? "h" : txt .length() == 2 ? "j" : i == 3 || i == 4 ? (txt .charAt(txt .length()-1) == ' ' ? "d" : " ") : i == 5 ? "å" : "e";}
        System.out.println(txt);
    }

I would love if you could make your own version, and see how bad it can get.

I’ve seen worse in production.

#3

The same in a one liner:


public static void main(String[]args){String txt="";for(int i=0;i<6;i++){txt+=txt.length()==0?"h":txt.length()==2?"j":i==3||i==4?(txt.charAt(txt.length()-1)==' '?"d":" "):i==5?"å":"e";}System.out.println(txt);}

This shit compiles and runs.

This is how I commit code to the evil corporations, to keep it safe from prying eyes. :point:

Adding some unnecessary instructions to my previous one:


public static void main(String[]a){String t="";for(int i=0;i<Integer.MAX_VALUE;i++){t+=t.length()==0?"h":t.length()==2?"j":i==3||i==4?(t.charAt(t.length()-1)==' '?"d":" "):i==5?"å":"e";if(i==6)break;if(i>6)break;System.out.println("A quick brown fox jumped over the lazy dog.")}System.out.println(t);}

Enhanced FizzBuzz for dummies:


	for (int i=1;i<=100;i++) {
		int a=((528>>i%15-1)&1)*4;
		int b=((-2128340926>>(i%15)*2)&3)*4;
		System.out.println("FizzBuzz".substring(a,b)+(a==b?i:""));
	}

I had a Java book with a lighthearted example of a program written as such that was a valid C, C++, and Java program.

This?? I found this polyglot online.


//\u000a/*
#include <iostream>

#define private
#define public
#define static
#define void int
struct {
  std::ostream &println(const char *c) {
    return std::cout << c < < std::endl;
  }
} out;
//*/
/*\u002a/
import static java.lang.System.out;
public class Polyglot {
//*/
  public static void main(/*\u002a/String[] args//*/
      ) {
    out.println("Hello from whatever language this is!");
  }
/*\u002a/
}
// */

Woo! It’s like playing in the mud!

@Riven: What… is… that?

#10

@SHC No, it was longer and more clever, but similar, making more use of the unicode literals.

#11

Python!

#13

Ow.
My brain ! why would you do that

#14

Text as unicode char, the compiler reads it as characters

public class JGO { public static void main(String[] args) { System.out.println("Lame :o("); } }

I once saw a video showing somebody using gimp as ‘IDE’ he draw an image pixel by pixel saved it renamed it to .class and it was the hello world program. I dont remember the video source neither the file format. Is there an image format without header, just a ‘byte array’?

#16

I bet only a *.raw image-file can start with 0xCAFEBABE

#17

I bet I am able to let every file start with ‘0xCAFEBABE’ :persecutioncomplex:

#18

You confuse data for information, but enough of this derailing :persecutioncomplex:

#19

Crap, there is a rail? I think I just missed it…

#20

Guessed as much, thanks. I just don’t see how to feed it to a compile without the IDE throwing a tantrum (And I foresee the answer will point out that using an IDE for that is foolish).

I once did try to use asian characters to name classes, just to screw with coworkers not using unicode in their IDE, but my own compiler had a seizure :clue:
