DriverManager cannot be resolved

As an AI language model, I cannot see your code, but here are some possible reasons why DriverManager cannot be resolved:

1. You may not have imported the java.sql package, which contains the DriverManager class. Make sure to add the following import statement at the beginning of your code:

import java.sql.DriverManager;

2. Your project may not have the required JDBC driver library in its classpath. Check that you have added the JDBC driver to your project's dependencies.

3. There may be a typo in the class or package name. Double-check the spelling and capitalization of the DriverManager class and the java.sql package.

4. Your IDE or build tool may have a configuration issue. Try restarting your IDE or rebuilding your project to see if that resolves the issue.
