I'm just starting out reading O'Reilly's 'Head First Java', and it says I should download the API documentation from java.sun.com...but I can't find it there. Please help!
This question has been asked many times. So you should have found it with the search.
But here it is. Just scroll down.

Please correct my English.
Although using the online pages will ensure you always get the most up-to-date version for that major version (Java 6 in this case) it's good to also have a local copy, in case you don't have a working Internet connection. I even put the Javadocs on my USB stick so I have it wherever I am.
