How to add any classes to the standard java libraries?

Question

As Java is an open source: if we have developed good classes which may help anybody.. Can we add them to standard Java library? If yes: how?

Answer 1

File a JSR.

Answer 2

There are quite a few mailing lists associated with ongoing Java/JDK development. These would be the best places to start for suggesting new classes and utilities to add to the JDK.

Answer 3

Just for interest's sake: MigLayout is considered by many to be a very useful LayoutManager, and its creators and a lot of its users are lobbying to get it adopted into the standard library. They hope to get it into Java 7. We'll see how that goes.

Answer 4

Submit patches to the OpenJDK project, via the mailing lists mentioned by jsight and then to make it official go the JSR route mentioned by Ignacio, ideally with some community support.

Answer 5

Most useful classes are maintained and distributed via libraries and not included in the JDK/JRE. The apache commons libraries are a very good example: extremely useful but not part of Java.

If your question is of theoretical nature - JSR's are the way to add something to Java. If your question is practical (iaw, you have something you'd like to contribute), I'd practically say: forget about it, put everything in a library and host it on sourceforge (or something else).
