# Java #JDBC

Hi! I am trying to finish my java hw about jdbc, but I always fail on join the two table together and write a code to let the user input the data in console to insert new row in my database.

Please help me to:

1. Create revenue report that generated from the cruise passengers by nationality and age

2. Create a report about sailors' data, the cruise they work on and their supervisors

3. make the user easily to input the passengers and cruise in the console, so the data will directly be added into the database.

*****Since I create many classes, so I put my code, SQLite database and jar in here: https://drive.google.com/drive/folders/1-zoEep1ILdnxKZszPc_QC05orbQy4rb-?usp=sharing*****

And here is what I try to write an insert method to insert the row in Cruise table, but it fails :( So I didn't put in my code in that link

private Connection connect() throws ClassNotFoundException { // SQLite connection string String url = ("org.sqlite.JDBC"); Connection conn = null; try { conn = DriverManager.getConnection("jdbc:sqlite:Database_Cruise.sqlite"); } catch (SQLException e) { System.out.println(e.getMessage()); } return conn; } /**  * Insert a new row into the warehouses table  */  public void insertRow(String sailing_date, String return_date, String departure_port, String ship_name, String cruise_serial_number) { String sql = "INSERT INTO Cruise(sailing_date,return_date,departure_port,ship_name,cruise_serial_number) VALUES(?,?,?,?,?)"; try (Connection conn = this.connect(); PreparedStatement pstmt = conn.prepareStatement(sql)) { pstmt.setString(1, sailing_date); pstmt.setString(2, return_date); pstmt.setString(3, departure_port); pstmt.setString(4, ship_name); pstmt.setString(5,cruise_serial_number); pstmt.executeUpdate(); } catch (SQLException e) { System.out.println(e.getMessage()); } catch (ClassNotFoundException e) { e.printStackTrace(); } }
