How can I log exceptions in C++ and Java?

How can I log exceptions in C++ and Java?

In C++, you can use try-catch blocks to handle exceptions and log them using libraries like spdlog or log4cpp. In Java, you can use try-catch as well, and log exceptions using the built-in logging framework or libraries like Log4j.

Can you show me a code example for both languages?

Sure! In C++, you might have:

try {
    // code that may throw
} catch (const std::exception& e) {
    spdlog::error("Exception: {}", e.what());
}

And in Java:

try {
    // code that may throw
} catch (Exception e) {
    Logger.getLogger(MyClass.class.getName()).log(Level.SEVERE, null, e);
}

What libraries do you recommend for logging in C++?

I recommend using spdlog for its performance and ease of use, or log4cpp for a more traditional approach. Both are widely used.

Are there any best practices for logging exceptions?

Yes, some best practices include logging at appropriate levels (info, warning, error), including stack traces, and ensuring sensitive information is not logged.
