    The comments in a piece of code should come from the design for the code.
    If you have defined what the code should do, add the thoughts that describe that design as comments to the code.

    How can anyone comment unfinished code? The comments should reflect what the code does.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    my tutor was like you should start to be able to comment on your code and I did when I started this but I have lost some of it

    basically it is a Numbers class should provide the following functionality:
     Generates 6 random numbers in a range 1 to 49.
     Write YOUR OWN custom method incorporating an algorithm to sort the numbers in ascending order.
     Store the 6 numbers in a fixed-sized collection (array).
     Format and display the numbers (number output in the range 1 to 9 should be preceded by a blank space).

    Sorry, why can't you add the comments in your last post to the code?

    Comments should say what the code does. If you wrote the code, do you know what you wanted the code to do and how the code was going to do that?

    If you didn't write the code, then maybe you should start over: make a design for the program, make a list of the steps the code should do, add that list of steps to the code as you write it.
    If you don't understand my answer, don't ignore it, ask a question.
