How do I configure logging in Java?

You can configure logging in Java using the java.util.logging package or by using frameworks like Log4j or SLF4J.

What are the steps to set up Log4j?

To set up Log4j, you need to include the Log4j library in your project, create a configuration file, and initialize the logger.

Can you show me a sample Log4j configuration file?

Sure! Here's a simple Log4j configuration in XML format:

<Configuration>
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1} - %m%n"/>
        </Console>
    </Appenders>
    <Loggers>
        <Root level="debug">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>

What are the advantages of using SLF4J over Log4j?

SLF4J provides a simple facade for various logging frameworks, allowing you to switch between them without changing your code.
