How can I implement custom logging levels in Java?

You can create custom logging levels in Java by extending the Level class from the java.util.logging package.

Can you show me a code example?

Sure! Here's a simple example:

import java.util.logging.Level;

public class CustomLogLevel extends Level {
    public static final Level MY_CUSTOM_LEVEL = new CustomLogLevel("MY_CUSTOM_LEVEL", 850);

    protected CustomLogLevel(String name, int value) {
        super(name, value);
    }
}

How do I use this custom level in my logger?

You can use it like this:

Logger logger = Logger.getLogger(MyClass.class.getName());
logger.log(CustomLogLevel.MY_CUSTOM_LEVEL, "This is a custom log message.");

What if I want to set a different threshold for my logger?

You can set the logger's level using logger.setLevel(CustomLogLevel.MY_CUSTOM_LEVEL); to filter messages.
