JavaFX ComboBox SQLite Database error - sqlite

Question

I've created a simple ComboBox which I am trying to populate with data from an sqlite file. The error I am getting is stating that it cannot find the file or it cannot find the table so I am unsure whats going on. The sql file is located in my project folder so I don't think thats the issue and my table looks fine so not sure if its that either.
//Error log
java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (no such table: CustomerPriceList)

Answer 1

Issue was that the sql file's extension was .db and not .sqilite
Correct format inside the Sqlconnection.java file:
Connection conn = DriverManager.getConnection("jdbc:sqlite:CustomerSQLDB.db");
