Those docs point to the tutorial
http://docs.oracle.com/javase/tutorial/, which is the only SE tutorial from Oracle I'm aware of. But even if you work through it, and program along with it, there's still much to learn about Java. Not that I recommend to read/worth through the entire tutorial in one go, mind you.
For JEE there's another extensive tutorial:
http://docs.oracle.com/javaee/7/tutorial/doc/home.htm (which I also don't recommend to work through in one go, there's too much in it that you will likely not need).
