    Default Beginner questions on getting started in Java.

    I just went through the codeacademy java course and I'm not sure how to get exactly started with java.
    I have done html, css and javascript before but I'm completely new to this type of coding and I'm clueless right now.
    I have some questions:

    How do I write java code. I've used notepad++ before, do I code in that?
    Forgive me this is very nooby but what's the java software thing in java.com?
    There's online and offline and 64bit, Do I need it or can I just code in notepad?
    I don't really like installing stuff if I could just do it in notepad so I've been afraid to install software.
    What's some good useful beginner projects I could get started on to develop my skills?
    What I want to eventually achieve is to make an app that I can put on my smartphone.

    I'm not super technological and I don't know to to get started in java to be honest.
    Any feedback would greatly be appreciated.

    Well, you are clearly going to need to install the latest release of the JDK which includes the development tools (compiler) and the run-time (needed to run your program). You do not need to be online to write or run Java. However, having access to a version of the JDK class file documentation is a must.

    And using your favorite text editor (Notepad, Vim, Emacs, etc) is fine and the best way to go to start. That way you will learn about class paths. You don't need css unless you are using JavaFX and doing more intermediate or advanced programming. JavaFX is included with the latest JDK.

    The tutorials in my signature below are helpful but don't explain very much. So you may want to buy a book (which I cannot recommend since I don't track them).

    So I would recommend doing the above, copying a program from code academy or write your own to check the installation and then continue from there.

    So I installed jdk and I was looking around and saw that you use command prompt to run the java code.
    Is this how people do it normally or do you people use something called IDE? There's this eclipse thing, should I install it?
    or is there something better software you reccommend to run code? Or should I just stick with the command prompt method since I use notepad? I'm very confused.

    Most developers probably use an IDE. But I recommend going without one first. It will force you to learn some essentials regarding class path, bin directories, etc. which IDE's do for you. Eclipse is a very popular IDE and it's free. There are quite a few others. Most folks down load them and see which ones they like better.

    Consult the tutorials in my signature below. They will show you how to compile and run the program from the command line.

    I second jim829's opinion - you would be better off with a good text editor (both atom and sublime are great) and a terminal for the first few months. IDEs make you lazy and make it hard to learn how to debug. That said, IntelliJ Idea community edition is also free, and it's hands down the most powerful IDE out there - but a steep learning curve for a novice. Once you know what you're doing, and constant formatting/trips to api/boiler plate code/compile time slip ups and typos just become busywork, then move to an IDE and let it to that stuff for you, but not before then!
