JavaResearch — Chinese JDK Documentation
Originally at javaresearch.gro.clinux.org
JavaResearch hosted Chinese-language documentation and source-code references for the Java Development Kit. The most-cited URL — the Sun JDK 1.4.0 java.lang.String source-code annotation page — was referenced from German-language Java forums and Chinese-language tutorial sites for years.
What it was
The site provided HTML-rendered, Chinese-annotated views of the Java standard library source code at the JDK 1.4 era. Developers used it as a quick-reference for understanding how core classes like java.lang.String, java.util.Hashtable, and the I/O packages were implemented at the source level.
Why it mattered
Sun's official JDK source code was distributed but not particularly easy to browse online in the early 2000s. JavaResearch's annotated, hyperlinked HTML versions of the source — with class names linking to other classes and Chinese-language commentary on key methods — were one of the few easily browsable references for Chinese-speaking Java developers.
Modern alternatives
OpenJDK's source code is now hosted on GitHub with full source navigation, and IDE-based source viewing (IntelliJ IDEA's decompiler, Eclipse's Open Type) has largely replaced the need for separate online source browsers.
