Use In Application Code

You can collect all kind of log(info, debug, trace .. etc). But, for your application performance, use only as exception error logging.

1. Get Log4j Logger

Logger logger = Logger.getLogger(getClass());

1. Log error with exception, Just type logger.error([message],e)

try{
    int a[] = new int[2];
    System.out.println("Access element three :" + a[3]);
}
catch (Exception e){
    logger.error(e.getMessage(),e);
}
