Reminds me of early 70's IBM manuals

| I know people who do these things without even thinking about them. |

Not bad for a beginner, but not really grasped the spaghetti code methodology:
- Use tabs and space characters constructively to mess up indentation in any other text editor.
- open in another text editor and partially correct indentations in arbitrary places.
- divide code base into multiple files, then multiple routines/procedures/ whatever within each file. For any given routine, do not call it from code within that file - always call it from within a different file. Break this rule occasionally. Particularly applicable to scripted web apps in php, python, jsp, etc.
Also applicable to scripted web apps - if you need a thing many times, don't just do it once, do it each time in a different language, taking care to call each language version from a different language.
Careful use of these techniques allows you to jump from deep within a nested structure without closing off cleanly behind you, while giving the appearance that you are doing so. Do not over-use this technique, or memory consumption and instability will become too obvious.

Who needs a huge list of those tips to write unmaintainable code in Java - I thought it did that by default?

What a strange thing to say.
Java is probably one of the easiest languages to write maintainable code with, and, while you can write "spaghetti" code in any language, there are plenty that beat Java with regard to the ease with which you can do so.
Javascript's obscure paradigms make writing clean code a real chore, and the Perl community almost worships the ability to write code that nobody else can understand. VB is rightly famous for providing numerous features that aid the creation of incomprehensible code. C++ with its function pointers, make writing indecipherable code a breeze.
Then there are the "functional" languages like Lisp and Prolog. Ouch!
Of course, if you really want to write code that nobody (even you, after a week or two) can understand, then any form of assembly language would be the weapon of choice. Code that redefines itself on the fly? No problem!

| It does partly depend on how well you comment it. I dusted down some Z80 assembler code I wrote over 20 years ago to show someone and it was very easy to understand because I had done what my teachers drummed into me - added plenty of comments. Even I was surprised at how easy it was to understand after so many years. |

It's also dead easy to customise an assembly language so only you know the equivalent machine code. Not quite so easy if you want the system to compile it though.

Crikey jh...
I ain't seen the AF, HL, BC, DE, IX and IY registers for donkeys years...
I wrote a FULL screen testcard program for the Sinclair Spectrum by
writing graphics into the border using HiSoft assembly. The main window
was drawn in Spectrum BASIC but the border in assembly...
RANDOMIZE USR <Basic Line Zero + Offset>
I remember it well... ;oD

Wrote a MIDI sequencer for the spectrum and later ported it to and Amstrad CPC. The listing, as I remember it, was humongous, with about 30% of that humongousness being comments. Someone made a comments elsewhere about Spectrum's sounding crap compared to C64s. Mine sounded like an orchestra
