java中未找到合适的驱动程序错误？

我是一名数据库初学者，因为我现在切换到Intellij idea，我正在尝试获取数据库信息，但它仍然给了我以下错误：

下面是我的JdbcSelectTest.java代码：

这是我的raj.sql查询

我已成功下载Mysql连接器，请查看我的

编辑：

使用Class.forNamecom.mysql.jdbc.Driver后；现在它显示了新的错误：

下载Mysql jdbc驱动程序jar文件并将其添加到您的类路径中

您似乎忘记了

//step 0 : register driver to driver manager
Class.forName("com.mysql.jdbc.Driver");

@user3585755在这种情况下，请检查您的类路径。该程序无法定位驱动程序jar文件。现在要设置该类路径，请intellij idea自行下载它，以便如何导航它的驱动程序位置？@user3585755，intellij自动下载该jar，以便数据库插件可以工作，它不会将其添加到项目的classpathClass中。forName会引发ClassNotFoundException，因此您需要处理它。用try-catch块包装这一行，或者声明抛出ClassNotFoundException的方法。您的jar和mysql驱动程序在文件>项目结构>库中吗？
