Find MAC address using Java

Recently i wanted to get the MAC addresses of the computer i was working from within my Java program. I started a small quest and all over there was this tip “this is system dependent so you need to make system calls”. Somewhere around there i found a “but”. Someone posted that in mustang (that is jdk 1.6 or jre 6) tings have changed a little and you can get all this info from a Java class without a system call.

A relaxing day…

Well, as you all know, Sunday was my birthday so the whole weekend was a relaxing one. We went to the beach for a meal, we came back home and sat outside on the garden talking just about anything. The night was relaxing enough. The moon was almost a full moon so it was very bright. One could just stand there and gaze at it. So here there is a small album i made out of pictures i shot at that day. I hope you enjoy them and as always high resolution pics are availiable upon request! Have fun!

Downtime Reasons

It seems that since i purchased the domain i’ve been having some issues. Sometimes the blog is down and inaccessible.  Do you get this too or is it just me? I called Godaddy‘s(my hoster) customer support, they were very friendly indeed (their customer support has always been there for me even though i am from the ‘cheap’ customers). But, at the time i called the site was resolving correctly so they couldn’t see any problems. I will be monitoring the situation and i apologise for any inconvinience. If you have the same problem at any time, come back a bit later and please report the problem to me. I realy need to iron this out

Thanks again and sorry for any problems!

Java crash course #5: Overloading vs Overriding

On the previous articles we mentioned both overloading and overriding but we didn’t pay sufficient attention to them. Those two meanings are among the most important ones in Object Oriented programming and design. It’s not a matter of usage it’s a matter of design and elegant programming. Let’s take a closer look on both of them.
