    Hello chronoz13,

    Glad you are giving Eclipse a try

    I think you are getting this error message because your code does not contain the main method?

    public static void main (String[] args){
    //code here..
    }
    Try including the main method and let me know what happens.

    ahh i got it sir java. i just tying to use it like JCreator
    even i didnt declared a package . i can mange to run it by just simply declaring public static void main
    then System.ou.print..so on..

    its not as easy a JCreator..
    hmm got a little trouble here ahaha
    anyway i can still run a simple application..ahaha

    i think i should go out first with JCreator.. ahaha eclipse is really complicated.. but i know someday ill be using Eclipse too.
    i have school mates thats using the same IDE like eclipse..

    i just need to use JCreator first.. to get familliar with basics... T_T,

    Eclipse has really good error handling and debugging features. You will notice that when Eclipse doesn't like something, a red line will appear under the code. Hold your mouse over it and a box will popup telling you the error aswell as suggestions for fixing it.

    Go with whatever IDE feels best for you.

    tnx sir java.. anyways about eclipse ... what does "package" means?
    coz i never use to encounter it in JCreator.. specially in making a simple application such as "hello world" app.

    A package is basically the location of your current Java classes.

    You create packages so you can keep all your projects nice and tidy. You do not have to declare a package though as you can use the default package. This places all your projects in the same directory.

    All you need to do is give your package a name and add your classes to the package. Its very simple, especially after you do it a couple of times.

    Did you read that tutorial link I sent you? If you follow it exactly you will be able to create a simple 'Hello World' application easily.

    I know you think Eclipse is a lot more complicated than JCreator but it really isnt. Its like anything - Once you do it a few times it becomes second nature
