Answer 1

You should use PreparedStatement primarily because it prevents SQL injection attacks. @John Moses has posted a tutorial to use PreparedStatement from the Java official documentation, here is another good link: MySQL and Java JDBC - Tutorial.

Moving your code to PreparedStatement, it should be like this:

PreparedStatement ps = con.prepareStatement("INSERT INTO Tiffany(Actor, Bio, More_Bio, Reason, Fact) VALUES (?, ?, ?, ?, ?) ");
ps.setString(1, Actor);
ps.setString(2, Bio);
ps.setString(3, More_Bio);
ps.setString(4, Reason);
ps.setString(5, Fact);
ps.executeUpdate();

Don't forget to close your resources after use them:

ps.close();
con.close();
