How to replace the usage of System.out or System.err by a logger?

Question

I have a simple if condition in which I use System.out.println . I would like to know how can I modify the code in order to replace this usage of a system.out by a logger ?

if(myVar.getDate().equals(20141127) && myVar.getNumber().equals(1)) {
                System.out.println("");
}

Any suggestions ?

Thanks

You can use some logger utility to log the details.

Have a look at Apache Log4j

The logging is as simple as

log.debug("This is an debug message");

where log is an instance of logger

For sample code you can look into this tutorial
