What methods are available for implementing a logging system in an application?

Logging in Java applications can be done using several common methods:

• Using standard logging libraries such as Log4j, Logback, or java.util.logging.
• Configuring logging levels (ERROR, WARN, INFO, DEBUG) to control the amount of output.
• Logging to files, console, or remote systems (e.g., Syslog, ELK Stack).
• Asynchronous logging to minimize performance impact.
• Formatting logs in structured formats (JSON) for easier analysis.

Example with Logback:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Example {
    private static final Logger logger = LoggerFactory.getLogger(Example.class);

    public void doWork() {
        logger.info("Starting work");
        try {
            // code
        } catch (Exception e) {
            logger.error("Error during execution", e);
        }
    }
}
