logger.log

logger.log("...")

All this time i never programmed in Java something that needed detailed logging. Recently, in one of my working projects, a logging facility became a necessity. The first thing i looked was the java.util.logging API.

Although i heard many people complaining about it, i found it pretty ok, at least for my needs. So i started digging the javadoc and some examples. After 20 mins i was nearly there, my logger instance was initialized, wrapped inside a singleton class that added a few more lines of tweaking in its behavior.

And then i started adding logging code inside my app. A typical class looked like:

import org.renegade.log.*;

public class Z {
	private Logger logger = Logger.getInstance();
	
	public void methodX() {
		[...]
		logger.log("...");
		[...]
	}
}

I had to keep with me all the time this Logger reference. After a minute thought i wrote something with a public static attribute that looked like:

import org.renegade.log.*;

public class Z {
	public void methodX() {
		[...]
		Logger.log("...");
		[...]
	}
}

That was a minor improvement, at least i got rid of the reference. When i made this change i remembered the static import. So here is my final approach ...

import static org.renegade.log.Logger.*;

public class Z {
	public void methodX() {
		[...]
		log("...");
		[...]
	}
}

Not bad at all :).
