Not connecting connection = getConnection(URL, USERNAME, PASSWORD);. How to connect the database to the environment?

Question

MySQL

I connect the database. If you comment out the line connection = getConnection(URL, USERNAME, PASSWORD);, everything works. I can't figure out what's wrong.
PS I follow the model, because there were a lot of mistakes, I work with several reference books, but I can’t fix it

If you remove the line, then you will get a message, but not the fact of the connection itself. And what are the mistakes?
