    Default Comment Location

    Which do you think? I have been swapping between these two styles for some time now and just can't seem to decide.

    PHP Code:
     * Comment before line: seems to be easier to mentally process the information.
        // list already contains item so...
        if (list.contains(item))
     * Comment after line: the code looks much more organized when the comment is in this location. Opinion I know but 
     * perhaps others agree.
        if (list.contains(item))
            // list already contains item so...

    Default Re: Comment Location

    Hi Googol,

    This is more down to personal preference. As long as the intention of both the comment and code is understood then it really doesn't matter.
    Java Code:
    if (list.contains(item)) // list already contains item so...
    The above is also acceptable.
    One thing I cannot stand is the overuse of comments. Things like:
    Java Code:
    if (list.contains(item)) //checks if list contains item.
            System.out.println("Present"); //prints out "Present".
    else // if list doesn't contain item
            System.out.println("Not present"); // prints out "Not present".

    Default Re: Comment Location

    What I hate even more is incorrect comment:

    Java Code:
    int i= 1; // initialize i to zero
    int j= i-1; //  j starts equal to i
    kind regards,
