You are missing closing bracket on case 2 (just as you close catch block). After that you should be able to continue solve the rest.

case 2:
                    int ret1 = 0;
                    do {
                        accnum = JOptionPane.showInputDialog("Delete Account\n\nEnter Account Number to be Deleted: ");
                        AccountNumber = Integer.parseInt(accnum);
                        try {
                            conn = DriverManager.getConnection(url, username, password);
                            stmt = conn.createStatement();
                            query = "Select*from AccountProfile where AccountNumber='" + AccountNumber + "'";
                            rs = stmt.executeQuery(query);
                            if (rs.next()) {
                                String q = "Delete from AccountProfile where AccountNumber='" + AccountNumber + "'";
                                String q1 = "Delete from AccountBalance where AccountNumber='" + AccountNumber + "'";
                                stmt.executeUpdate(q);
                                stmt.executeUpdate(q1);
                                JOptionPane.showMessageDialog(null, "Account Successfully Deleted!");

                            } else {
                                String rec1 = JOptionPane.showInputDialog("No Record Found!\n\n1 - return\n2 - exit");

                            stmt.close();
                            conn.close();

                        } catch (SQLException ex) {
                            JOptionPane.showMessageDialog(null, "SQLException: " + ex.getMessage() + "\nSQLState: " + ex.getSQLState() + "\nVendorError: " + ex.getErrorCode());

                        }
                    }//missing closing bracket

Thanks for saving my Grades!

Woah! That totally fixed many of the errors. O.o I rechecked it for many times and I didnt saw that.. Thanks! Thank you sooo much!

wondering_ed, I think you may have just found this out yourself, but basically any time you see " ____ expected " it usually means you forgot a closing bracket } or a closing ) somewhere.
