public boolean addUserString nameString password DBHelper db=new DBHelper; conn = dbgetConnection;这是一个用户注册的部分代码把它补充

完整的代码如下：

public boolean addUser(String name, String password) { boolean success = false; try { DBHelper db = new DBHelper(); conn = db.getConnection();

    // 创建一个PreparedStatement对象来执行SQL语句
    String sql = "INSERT INTO users (name, password) VALUES (?, ?)";
    PreparedStatement stmt = conn.prepareStatement(sql);
    stmt.setString(1, name);
    stmt.setString(2, password);
    
    // 执行SQL语句并返回受影响的行数
    int rows = stmt.executeUpdate();
    
    if (rows > 0) {
        success = true;
    }
    
    // 关闭PreparedStatement对象
    stmt.close();
    
    // 关闭数据库连接
    conn.close();
} catch (SQLException e) {
    e.printStackTrace();
}

return success;

}
