System.out.println() ?

Can someone explain me the difference in using logs instead of using System.out.println ?

I've used the println method for checking some errors in code while doing projects in Eclipse, but I've been told that using logs is better, why?

With the various Log methods available, we can filter to varying levels of verbosity. It is also the standard for Android programming so much so that some devices/emulators redirect all System.out.println() calls to Log.i(). Since it will be used anyhow, it is best to just follow the convention so other developers will have an easier time reading your code.
