Its more likely the statement object ("stmt") is null. How do you create the Statement object?

check your statement object, as Paul said. And yes, please give a space between your table_name and "VALUES" keyword.

You are correct that you need to use executeUpdate. Also, as name is a string, it needs single quotes. You might consider using a prepared statement to avoid these formatting issues.

This isn't the source of your problem, but it is something you will hit later.
