How to create multiple log files with different contents using log4j

I am trying to create multiple log files with different contents with log4j.
This is my log4j.propertiesfile.

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/home/dhanushka/Documents/log4j.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n

log4j.appender.testng=org.apache.log4j.RollingFileAppender
log4j.appender.testng.File=/home/dhanushka/Documents/TestNGlog.log
log4j.appender.testng.MaxFileSize=1MB
log4j.appender.testng.MaxBackupIndex=1
log4j.appender.testng.layout=org.apache.log4j.PatternLayout
log4j.appender.testng.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n

# Root logger option
log4j.rootLogger=INFO, file, admin, stdout, testng


# Log everything. Good for troubleshooting
log4j.logger.org.hibernate=INFO

# Log all JDBC parameters
log4j.logger.org.hibernate.type=ALL


This is how I implemented the code.

public class VerifyAmenities {

private static Logger defaultLogger = Logger.getLogger("file");
private static Logger testNGlogger = Logger.getLogger("testng");
.
.
}
defaultLogger.info("This is default Logger");
testNGlogger.info("This is testNG Logger");

Thus, it creates two log files. But both have the same magazines. Appreciate any answer.

Finally, I found a way to do this.

# Root logger option
log4j.rootLogger=TRACE, stdout, file

log4j.category.testngLogger=DEBUG, testng
log4j.additivity.testngLogger=false

In rootLogger, it's like the father of all magazines. It inherits by default. The root registrar parameter should be like this.
If you are additivityset to false, it will never go torootLogger

In the file, log4j.xmlit will look as follows.

<logger name="testngLogger" additivity="false">
    <level value="DEBUG" />
    <appender-ref ref="testngLogger" />
</logger>

<root>
    <priority value="INFO" />
    <appender-ref ref="CONSOLE" />
    <appender-ref ref="fileLogger" />
</root>
