How can I implement log filtering in Java?

You can implement log filtering in Java using the java.util.logging package. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import java.util.logging.*;

public class LogFilterExample {
    public static void main(String[] args) {
        Logger logger = Logger.getLogger(LogFilterExample.class.getName());
        logger.setFilter(new MyLogFilter());
        logger.info("This is an info message.");
        logger.warning("This is a warning message.");
    }
}

class MyLogFilter implements Filter {
    public boolean isLoggable(LogRecord record) {
        return record.getLevel() == Level.WARNING;
    }
}

This code filters out all log messages except warnings.

How can I customize the log levels?

You can customize log levels by setting the level on the logger using logger.setLevel(Level.YOUR_LEVEL);. Replace YOUR_LEVEL with the desired level like Level.INFO or Level.SEVERE.
