SQLite数据库表未连接

Question

我正在尝试创建一个程序，该程序将在表格中生成学生信息。我已经在SQLite Studio中创建了一个数据库和一个名为data的表。我还成功地将数据库连接到了我的程序，但是，当程序运行时，出现了一个SQL错误，说该表丢失了。请指教。

import java.sql.*;
import javax.swing.*;

public class connection {

Connection conn = null;


public static Connection dbConnector() {

    try {
        Class.forName("org.sqlite.JDBC");
        Connection conn = DriverManager.getConnection("jdbc:sqlite:\\Macintosh HD⁩\\Users\\ethantang⁩\\Desktop⁩\\eclipse-workspace~⁩\\FBLA project⁩\\students.sqlite");
        JOptionPane.showMessageDialog(null, "Connected");
        return conn;

    }
    catch(Exception e) {
        JOptionPane.showMessageDialog(null, e);
        return null;
    }


}

}
