Java examples: Enhanced For Loop

Back to school


Finally I am doing MSc. I didn’t do quite well in BEng as I hoped. I didn’t listen to my lecturer at the time.

You can’t look after anyone else if you don’t look after your self

Those were her exact words and something that failed to listen at the time but never forget any more. It’s been haunting me forever. Hopefully MSc in BioInformatics would allow me to put that right. Leave the nightmare behind.

I think I was quite lucky to get in to MSc. I got  ripped apart in my interview. My references came in very late. I am still not properly enrolled because I am waiting for the documents to come through. So I got to make the most of this. But this would be just the beginning.  2 evenings per week (learn Unix, Perl and Java). It’s going to be fun. Brings back some some bad memories and some good memories. Oh and I am totally not using the MSc as an excuse to break my bank to buy one of those Alienware :D.

In the coming weeks I will be putting up the Tutorials I’ve learnt here. Mainly as a personal record and also hope it would be use to someone.
