关于java:Compile time error: package javax.servlet does not exist import javax.servlet.*

Compile time error: package javax.servlet does not exist import javax.servlet.*

我设置的类路径如下：
CLASS_PATH: C:\\\\\\\\Program Files\\\\\\\\Apache Software Foundation\\\\\\\\Tomcat 10.0\\\\\\\\lib;C:\\\\\\\\Program Files (x86)\\\\\\\\Java\\\\\\\\mysql -connector.jar;C:\\\\\\\\Program Files (x86)\\\\\\\\Java\\\\\\\\sqljdbc_8.2\\\\\\\\enu\\\\\\\\mssql-jdbc-8.2.0.jre8.jar;<铅>

而且我还尝试在编译时使用 jar 文件：-
java -cp C:\\\\\\\\Program Files\\\\\\\\Apache Software Foundation\\\\\\\\Tomcat 10.0\\\\\\\\lib\\\\\\\\servlet-api.jar Hello.java

java -cp"C:\\Program Files\\Apache Software Foundation\\Tomcat 10.0\\lib\\servlet-api.jar" Hello.java

java -cp .;C:\\Program Files\\Apache Software Foundation\\Tomcat 10.0\\lib\\servlet-api.jar Hello.java

java -cp".;"C:\\Program Files\\Apache Software Foundation\\Tomcat 10.0\\lib\\servlet-api.jar" Hello.java

java -cp C:\\Program Files\\Apache Software Foundation\\Tomcat 10.0\\lib\\servlet-api.jar;. Hello.java

java -cp"C:\\Program Files\\Apache Software Foundation\\Tomcat 10.0\\lib\\servlet-api.jar";. Hello.java

我也尝试用类路径替换 -cp，但每次仍然出现以下错误：

tbh 我也在 netbeans IDE 上尝试过其他 Servlet java 程序，它运行完美，但即使在搜索并尝试了所有可能的解决方案之后，我也无法自己明确配置它，请大家帮我解决它。
