    On a side note.
    Always look at code with errorS, as being code with AN error.
    Look at the first error as if it were the only error.
    Fix that error, and then look at it again.

    First reason: When you fix one error, sometimes that clears up as many as ALL errors reported. Not always...

    Second reason: When you make changes here and there, and there and there and there, and take another look, you first of all could have made unnecessary changes and two if your changes leave errors, you will not know what change may have been in error and what changes were helpful, if any at all.

    Following this simple approach will ease the burden of debugging most of the time.

    Line#26 you have the same error you had before by adding the variable types in the method call.
    Remember when you DEFINE the method, you have to tell it what types the variables will be. But when you USE (call) the method, you DO NOT include the variable types.
    (remember when you removed the double[]s from the method call on your current line#24.)

    This error exists in your code as of post#52 multiple times. Many method calls you have included the variable types. Without scrolling I see this happen 4 times.

    Look over them method calls and be sure you are not trying to declare a type in a call. Be sure not to remove the types from the definitions!


    Edit: post your code again after you find and correct the errors of this type and include any questions you have (if any) about why this is the way it is.

    I see nothing wrong with that line, other than convention says to place your opening brace on the same line, ie:
    public static void displayFailedStudents (String[] name, double[] caMark, double[] ctMark, double[] asgMark, double[] finalMark) {
    ...but since it is on the following line in your code, nothing wrong with that line as it stands.

    refer to post #53.

    You are getting only one error.

    Post your code again as I currently have no idea what has been changed.

    as of your code posted in post#63:

    Line#19: A method call as:
    finalMark = calculatefinalMark( count, caMark, ctMark, asgMark );
    compare to line#89:
    public static double calculateFinalMarks(int count, double[] caMark, double[] ctMark, double[] asgMark)
    and the related error message states:
    The method calculatefinalMark(int, double[], double[], double[]) is undefined for the type S10122534c_Assignment
    This error message means the compiler can not find a method with that signature. Where signature means the method name, return type, and listed parameters. Compare what you defined that method to be on line#89 and compare it to how you tried to use the method on line#19. Java is CASE and SPELLING sensetive.
    (there are two errors on line#19)
    Try to correct this, and ONLY this. Post the code again.

    as of your code posted in post#65:

    line#18:
    FinalMark = calculateFinalMark( count, caMark, ctMark, asgMark );
    Again two errors, again java is case and spelling sensetive.

    First error:FinalMark cannot be resolved to a variable
    This means the compiler can not find a variable with the name "FinalMark".

    Second error:The method calculateFinalMark(int, double[], double[], double[]) is undefined for the type S10122534c_Assignment
    This means the compiler can not find a method with the signature: calculateFinalMark(int, double[], double[], double[]). As if your method does not exist at all!
    Well it in fact does NOT exist in your code. You have a method very close to it, but the spelling is different. You have to make sure to type the names exactly the same. If a letter is upper case in the definition, it must be upper case in the use. If the letter 's' is at the end of the name in the definition, it must be there in its use. This rule applies to variables and methods throughout java. Typos of this nature make it seem you have bigger problems than you do.

    class, interface, or enum expected
    This error message from the compiler means it has found the end of a class's definition and is looking for the next definition of either class, interface, or enum. Check for extra }s that could have ended a class definition before you intended.
    If you don't understand my answer, don't ignore it, ask a question.

    I want to point out that finalMark has nothing to do with calculateFinalMark.

    When you declared the variable finalMark, you declared it with a lower case 'f' on the front. Any time you use that variable, you must use it with a lower case 'f' on the front.

    When you declared(& defined) your method calculateFinalMarks (on line#88 as of your most recent post) you have a cap 'F' for the final and you have an 's' on the end.

    You have to look at the error message, and understand what it means. If you do not know what it means, that is a question you can post and someone will answer it. I get the feeling you are lost and just making changes you are told to make. Tell me what it is you don't understand about what is going on and I will try to help you understand.

    I meant that changing FinalMark = calculateFinalMark to finalMark = calculatefinalMark is not what the problem is.

    ok step back and just have a look at only two lines of code.
    So we are looking at the same thing look at the code you posted in post#68

    look at the method name you are using on line#18. Compare that to the method name you defined on line#88

    They are not the same name. Do you see the difference in the two?
