    Default Java (Easy)

    Ok, Lets get into our first script.
    Hello world!!!!
    1. Hello World
    // Public class just helps it seem natural right now. We'll be going into just Normal Class later.
    public class HelloWorld {
        // Public static VOID main sends a string that connects each script. 
        // Pretend its a rope. Without the script the rope will lose durability. It'll all fall down so it wouldn't be usable.
        public static void main (String[] args) {
    	  //Declares a main class.
               System.out.println("Hello World");
    //displays text so you can read it.           //Try compiling this. It worked for me. If it doesn't work for you (If you dont know how to //check Java version listen up) search up JAVA in your search thing and click it. It its Java 6/7 then this should work. It may just be a //complicated error like my thing that wont show the image.
       }
    }
    2. Variables

    Ok, I'm gonna edit this lesson so you can ACTUALLY run it.
    Listen to my comments too. I'll start making videos and replace the code boxs.
    public class Pig{
      public static void main(String[] args) {
    	  //starting speech
      System.out.println("Lets add 2 Numbers!");
      //Declares Variables
      int a = 26;
      int b = 153;
      // The variable its added up in
      int sum = a + b;
      // Lets it print the sum :D
      System.out.println("Sum: " + sum);
      // Test it out!!!
      }
    }

    I'm glad you're trying to write tutorials, but those will probably do more to confuse people than help them learn. Your first code snippet contains several syntax errors, which means that the code in fact will NOT compile, despite what you indicate in the comments. Also, saying "check if your IDE or Java is working" is very unclear, especially when the problem is in fact your code. Your second code snippet provides no context for what's going on. If anybody is looking for basic tutorials, I suggest sticking with the ones written by Sun: The Java™ Tutorials

    Ditto Kevin's comment...its nice to see someone making the initiative to write tutorials, but if you are going to do so:

    a) spend some time with it - make it legible, compilable, readable, use proper syntax, use proper grammar, use proper code conventions, use javadoc commenting, etc... and most importantly, make it so anyone can follow it. Make it look 'textbook' (and no offense, but the above is far from achieving any of these points) - if you want someone to take them with authority and follow them, they have to be made to look like they were written by a teacher, not a student.

    b) write something that has not been done ad nauseum - there are countless demonstrates of 'hello world', and there are the standard java tutorials that most people will navigate to which Kevin pointed out. Think a bit outside the box and write things unique to distinguish them away from the rest.
