We keep telling you to clean up your curly braces and code formatting and you keep ignoring that piece of advice.

YOUR BAD CODE FORMATTING AND BRACE USE IS WHAT IS CAUSING THE MAJORITY OF YOUR PROBLEMS.

CHill60 13-May-21 3:39am

On your previous post I explicitly told you to be consistent in your use of braces and you have been told time and time and time again to tidy up your code.
We're not saying this to make things pretty, we're saying this because it makes the problems you are having blindingly, obviously, instantly solvable.
I seriously hope you don't have any more issues because I for one am going to be completely ignoring any post from you from this point forward

Because you still have errors in your code.
Advice use online code beautifiers to enforce nice coding style, it allow to highlight some coding mistakes.

                                if (year % 4 == 0) {
                                    if (year % 100 == 0) {
                                        if (year % 400 == 0) {
                                            //
                                        }
                                        //  
                                    }
                                    //
                                }
                                //
                            }

As one can see, IsVowel is out of the class, and other such errors later too..

Solution 2

Do you ever look at your code?

Java

    return q;} // Why is this closing brace here?
} // especially when this should be the method close
