How can I configure logging in C++ and Java?

To configure logging in C++, you can use libraries like spdlog or Boost.Log. In Java, the built-in java.util.logging package or frameworks like Log4j and SLF4J are popular choices.

What are the advantages of using spdlog over Boost.Log?

spdlog is known for its high performance and ease of use, while Boost.Log offers more features and flexibility for complex logging needs.

Can you give me a simple example of logging in Java using Log4j?

Sure! First, add Log4j to your project. Then, create a logger instance and use it like this:

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class MyClass {
    private static final Logger logger = LogManager.getLogger(MyClass.class);

    public void myMethod() {
        logger.info("This is an info message");
    }
}

What logging levels should I use in my applications?

Common logging levels include TRACE, DEBUG, INFO, WARN, ERROR, and FATAL. Use them to indicate the severity of log messages.
