Java's equivalent to php.net?

Where can I find useful resources to Java.

• 开发者_如何学编程all Java functions and syntax explaining (like php.net)
• mac widgets with all functions gathered (like php function reference)

Would be great if you had links to very good resources/tutorials to share.

you should start with the Javadoc

---

JavaDoc in CHM format for easily searching

http://www.allimant.org/javadoc/index.php

Javadoc is an invaluable reference as already said

I think you should just get Eclipse or your favorite IDE and add the Javadoc to the build path of the jar

EDIT:

Window\Preferences\Java\Installed JREs

Select the JRE

Press Edit

Javadoc URL: point to the URL

Shift + F2 should take you to the appropriate function definition , and i must say it is very productive =]

Just use the auto-completion feature of your editor.

In Eclipse: Write "[name of your object].", Press [CRTL]+[SPACE] and then read the javadoc of the suggested functions/methods.

Java API Documentation explains all classes and methods.

Java2s.com has very good examples for Java
