Java Homework only!

[Belay Tekalign]

Eyob and anyone who want to jump in, can we dedicate this thread for exercises only. The Google groups is amorphous for such endeavor.

Exercise One: Create a superclass named EyobIsGreat. Make it abstract with only one parameter yourName. Create one method which writes something. Here is the complete answer. https://docs.oracle.com/javase/tutorial/java/IandI/super.html

Programming is not about inventing things but using them to deliver product to your customers using the existing knowledge. It is open book and open everything. Remember that. This is very important. Delivery is your mission not memorizing things. Your code must compile.

Correction:

There is an intended auto correction on the last thread. I meant Shift and it is typed now as shit. I didn't mean that. Here is the whole thing. Forgive me

BTW: Eyob were you able to decipher it. It is elementary play on position.

Here is a simple cipher (cryptography) to encrypt messages using bit shifting

http://www.math.cornell.edu/~mec/Summer2008/lundell/lecture1.html

This is a right shift by 3 letters. 

encrypted = original >> 3

The shifting (although not binary is very applicable in encryption). Such shift is called circular shift because you don't drop the overflow. So the letters XYZ will be placed back under ABC.

Now question for you. Decrypt the following message by hand. What does it say?

Isn't that exciting?

Hi Belay,

Good idea. We can make this an open call for those who want to learn coding and contribute to open source.

I haven't reached this part yet, but don't worry, I will. It's just that with my job and the practice I need to make it'll take a little time.

Best regards,
Eyob

Dear Belay,

Ah it's no problem at all. Don't worry about it.

And I did decipher it and sent a response on my first email of the day. Did you get it?

Best regards,
Eyob

Eyob:

I got your cipher but you did it in reverse. First type THANK YOU then cipher by moving each letter 3 forward. You did the other way. Do you mind if I said this? We are here to share learning. I hope I didn't offend you. Let me know if I am wrong

I don't mind at all. I'm not afraid of being corrected ☺. If anything this alerts me that the direction does confuse me a little, so now I can better focus on it.
