First you need to create a class that allows you to connect to the database. (Here)

Then you can use the stmt.executeUpdate(query) method to add something in your db. You can find more here. (In the link I mentioned above is part of the update method update(Connection connection, String sql, List<Object> parameters))

I highly recommend you to see how sql queries work here, specifically the one about INSERT INTO.
