| AmbySoft Coding Standards for Java | Very detailed, served as the foundation for "The Elements of Java Style" (2000) | |
| Cay Horstmann's Java Language Coding Guidelines | According to the author, a simplified version of one that has been used with good success both in industrial practice and for college courses (2004) | |
| Code Conventions for the Java Programming Language | A style guide written by Sun, only covers the basics. Often seen as the official reference, though not taken too seriously by Sun itself (1999) | |
| Geosoft Java Programming Style Guidelines | Unlike all other documents mentioned here, comes in an annotated form that makes it easy to use during project code reviews (2004) | |
| Infospheres Java Coding Standard | Provides little discussion, but features interesting Javadoc guidelines (1999) | |
| JavaRanch Java Programming Style Guide | Covers mainly the same ground as the original Sun document, but gives different advice in some areas | |
| Nejug Coding Standards for Java | The most complete and up-to-date Java coding style document we know of. Compiled by the New England Java User Group (2001) | |
| Red Hat J2EE Engineering Standards | Very pragmatical and accessible collection of best practices (2003) |
| Code Complete |
Steve McConnell, Microsoft Press, 2004, ISBN 0735619670 Just like "The pragmatic programmer" a book that should be included in every software engineering library. Devotes a whole chapter to code layout and style | |
| Expert One-on-One J2EE Design and Development |
Rod Johnson, Wrox, 2002, ISBN 0764543857 Devotes a whole chapter to design techniques and coding standards for J2EE projects | |
| The Elements of Java Style |
Allan Vermeulen, Scott Ambler et. al., Cambridge University Press, 2000, ISBN 0 521 777682 Provides a set of rules for writing Java code that can be used as the Company's coding standard. Falls short on some rules, but overall gives sound advice |
| Artistic Style | Source Code Indenter written in C++. Supports C/C++ and Java | |
| BeautyJ | Java Source Code Formatter that demonstrates the use of a flexible Java source code framework. Uses a JavaCC generated parser | |
| CheckStyle | Java Coding Convention Checker. Uses an ANTLR generated parser | |
| Eclipse | Very powerful Java IDE that since version 3.0 ships with a powerful Java Source Code Formatter | |
| FixStyle | Code style improver for Java. It currently only sorts modifiers into the order recommended in the Java language specification. Uses a JavaCC generated parser | |
| IntelliJ IDEA | Very powerful Java IDE equipped with a powerful Java Source Code Formatter (commercial) | |
| ImportScrubber | Java Import Optimizer. Uses BCEL to parse class files | |
| Jacobe | Java Source Code Formatter. Written in C, available for Windows and Unix (not Open Source, but free) | |
| Jalopy (Open Source) | The predecessor of the commercial Jalopy. Originally written by the founder of TRIEMAX Software (until 1.0b10), now maintained by the community | |
| JCSC | Java Coding Convention Checker. Uses a JavaCC generated parser | |
| Jindent | Java Source Code Formatter. They advertise it as "the most powerful source code formatter for Java". Uses a JavaCC generated parser (commercial) | |
| JRefactory | Java Refactoring Tool that contains a source code formatter. Uses a JavaCC generated parser | |
| Mozart Development Environment | Framework for user extensible compilers and development tools | |
| PMD | Java source code analyser/checker. Uses a JavaCC generated parser | |
| Polystyle | Formerly called Trita and SmartBeautify. Source Code Indenter that - among other languages - supports Java and JSP. Unlike other tools, Polystyle uses sample files that express your favorite coding style for configuration. Written in Java, but compiled to native code (commercial) | |
| QDox | Framework for extracting class/interface/method definitions. Uses an JFlex/BYacc/J generated parser | |
| Recoder | Source Code Metaprogramming Framework. Uses a JavaCC generated parser | |
| RevJava | Review assistant for Java programs. Uses BCEL to parse class files | |
| Transmogrify | Java Refactoring Tool that comes with a basic code formatter. Uses an ANTLR generated parser. Seems to be no longer actively maintained |
