That's a download for Java tutorials. To actually do them you'll need a compiler. I use jGrasp but there are many others you can use. Eclipse is pretty popular and they all do the same thing basically. A compiler can be downloaded on the internet, and you'll need to download Java from Sun Microsystems as well. Just to let you know you gotta be pretty dedicated, it takes a lot of time to make good apps. Google's App inventor is an alternative to learning code.

This may get you started:
http://download.oracle.com/javase/tutorial/

But if you're never programmed in any language, you need to take an intro to programming course.

I don't have anything I can recommend. But there's tons of info online. Just do a google search for 'Intro to programming'. That's how I found this:

You cant try this Stanford University lectures on youtube: http://www.youtube.com/user/StanfordUniversity#g/c/84A56BC7F4A1F852 ..or just search for "Mehran Sahami Programming Methodology" in itunes U if you use itunes.. Same lectures. I think its a really good starting point.

Bro you should check out "Starting out with Java: From control structures to objects" by tony gadis. Just google it. Its the one I used in my intro to programming course. It starts out as basic as can be. Its really good

I was in his shoes...about 15 years ago LOL Wow, where does the time go? 2 degrees and a couple careers later I guess.

What I would stress are a few things:
1. Learn how to do some flow charts before you write code
2. Learn the basics of program flow (if/else, do/while, switch/case statements)
3. Learn the "types" of your language (int, String, float, char, modulus etc.)
4. Learn some data structures (arrays, Lists, Vectors etc.)
5. Learn about functions and/or classes. Remember that a function should be fairly short and very specific to a task, like: getUserName, calculateCheckingBalance etc.
6. START SMALL AND WORK TO LEARN SOMETHING NEW EVERYDAY!

I can't stress how important #6 is. Do a "Hello World" program just to get used to writing some code.

Think of some simple programs like: write numbers 1 to 10 to an array and print them out backwards, ask user to input what year they were born in and print them back their age. Advance up to something like a ATM simulator where you can make deposits, withdrawals, check your balance. I did all similar type things in Programming 101.

I still love the Dietel and Dietel books...get one for JAVA and it's money well spent in my opinion.
