beginner guide java

[okeee]

I want to learn Java programming as a beginner. I need a beginners - basic user guide. So the guide should be extensive, cause I want to be able to program up to good basic java programmer level. Also it would be great if I can actually try out some of the java code, to input it somewhere and check if it works.

This page (http://www.onlinecomputerbooks.com/free-java-books.php) may provide a good starting basis, since it offers links to several online books you can peruse.

This forum (http://www.javaprogrammingforums.com/) may also be of use to you, since it gives lots of examples of algorithms which may help answer your own questions or, indeed, you can incorporate them into your own projects.

Lastly, if you want some hard copy to guide you through development, I would recommend this book (http://www.amazon.com/Effective-Java-2nd-Joshua-Bloch/dp/0321356683/ref=sr_1_3?s=books&ie=UTF8&qid=1286295777&sr=1-3) to help hone your coding skills.

I tried some exercises and you sometimes need specific expressions, such as "Math.random" to complete te exercise. But how are you supposed to know these expressions, and I have no idea how to search for them if in the exercise only a description is given, and not specificly stated "use this expression to do this exercise".

It appears to me you're trying to run before you can walk. If you've never programmed in Java before and want to know about classes such as math.random, you really need to start off with first principles.

In this instance, this is a way in which you can call particular algorithms to carry out particular tasks (in this case, generate random numbers), without actually having to write the code yourself. You just reference the class, and it'll take care of it for you.
