when I answer a question , I try to talk generally about the code , not only on what specifically doesn't work.
writing something that works is a minimal request . writing something that works and is written good is a different thing.
all of these small stuff - conventions , best practices etc. - these stuff make the program better. let's say he'll add another constructor in the future - any object that used default constructor in the past will cease to work and it will take few minutes in the good case , and few hours in the worst case to figure out what went wrong.
also , camel case is not mandatory thing , but it is common practice. why not style your code in a common way and make your code more readable in the future for your self?
