    Add what "stuff"? You need to be more specific in your answers.
    Which error are you working on?

    Where are you adding your braces? To which part(s) of the code?

    Can you post the code with the updates? It's impossible
    to guess what is going on without any visual aid. Also
    comment the line(s) that have errors when you compile it
    and if possible the errors also.

    What does the error message actually say? If that
    is a method parameter, then it should not have the
    semicolon. Can you not show more code than that?

    error: ';' expected
    String bottlewordString(int bottleNumber);

    Going by the last piece of code you posted:

    * why are there semicolons after your 'if' statements?

    * Have you solved the "class needs to be in own file" error?

    * Again - the semicolon after the method parameter is going to cause errors.

    If you put semicolons after an 'if' statement, the program is always
    going to evaluate the statement as true - or preform some other
    undefined behaviour.

    Putting a semicolon after a method parameter should always cause
    a logic or compilation error. If you place the BeerSong class in it's
    own file (which was the first problem) most of the errors will be
    easier to understand.

    Nope, not true and the behaviour will always be defined.
    if(3 == 5);
    This will never be true regardless if the semicolon is there or not. However the presence of the semicolon signals the end of the if statement. The below code is the equivalent.
    if(3 == 5) {
        ;
    }
    This effectively says if the condition is true do nothing. What causes the confusion is that the code following the semicolon (which people assume is inside the if statement) is actually outside the if statement and will always be executed regardless of the condition in the if statement.

    What we want you to do: Read and apply the advice given, make progress, report back with your results, updated code, new errors, and new questions. We've been over this before. We're not going to write it for you.

    Is this a college assignment? If so when is/was it due?
    You have been working on this for over two weeks now at
    least.

    Have you spoken to your professor or teaching assistant about it?
    Have you been given extensions or guidelines to follow?

    Read the assignment question from the text book and try to work it
    out on pen and paper first. If you work out what is supposed to happen,
    write it in pesudocode (spelling?). Then slowly translate that code into
    executable Java statements. Follow the guidelines from Greg, myself and
    others.

    Have you made any progress since the last problems?
    Are you getting any new errors or problems? Have you
    resolved any of the ones posted previously?
