Cannot resolve symbol 'Logger'

The "Cannot resolve symbol 'Logger'" error usually occurs when the Logger class is not imported or when there is a problem with the logging library configuration.

To resolve this issue, you can follow these steps:

1. Make sure you have imported the Logger class correctly at the top of your file. In Java, you can import the Logger class from the `java.util.logging` package by adding the following line:

import java.util.logging.Logger;

2. Check if you have the required logging library in your project dependencies. If you are using a build tool like Maven or Gradle, make sure you have added the logging library as a dependency in your project's configuration file (pom.xml for Maven or build.gradle for Gradle). For example, if you are using the Java Util Logging framework, you can add the following dependency to your pom.xml file:

<dependencies>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.32</version>
    </dependency>
</dependencies>

3. If you are using an Integrated Development Environment (IDE) like IntelliJ IDEA or Eclipse, try refreshing or rebuilding your project to ensure that all dependencies are properly resolved.

By following these steps, you should be able to resolve the "Cannot resolve symbol 'Logger'" error and use the Logger class in your code.
