Thread: i still hate java

and my passionate detest for grows with each line painstakingly thrashed out!

assignment (rate this out of 10 for fun, guys)

using the fsm classes code a calculator that operates on whole numers and can use all the main maths operators. the calculator should be able to accept decimal, binary and hex values and return the correct result. include the appropraite fsm state diagrams

oh joy!

(anybody wanna do it form me)
(stop - flame - that was a joke)

im not gonna be beaten by poxy java!

I took Java 1 and 2, but we never talked about the "fsm classes"... What are they?

Otherwise, that doesn't sound too terribly difficult...

hmm...sounds like a bit of the old C++ to Java conversion would come in handy here. just stick in a loop that wastes a few seconds in between every step of building the GUI and after every user inputs. that oughta slow things down to java speed. they'll never know the difference

Saying that you need to know C++ to learn Java is the same as saying "You need to learn C before C++" - it just isn't true. You should however, be familiar with Object Oriented program design. There are several publications by Sun regarding OOP. Check out the tutorials on their site (they are really good and will help a lot in understanding programming in Java, and Object Oriented concepts and application of those concepts in Java code).

the syntax is fairly similar to C++, its just the language is based upon object orientation and classes, it seems that even the most simple applications are ridiculously over-complex due to the fact they must object orientation.

Is this a GUI calculator or just a command line project?

Also - wtf's an fsm class?

a command line project that must be written under unix in emacs
(shudders)

an fsm is a finite state machine - that is a theoretical machine that has a start state a halt state an X states in between. For the transition between states the machine must recieve an legal input value.

eg Start state accepts 1 as legal input value - 1 is recieved it moves onto state GOT1, this accepts a and s so it moves onto the next until it reaches a halt state where it will accept no more input and the fsm ends.

the fsm classes model real fsm's

so

fsm.add("digit", "0-9", "nextdigit")

would an action to the fsm object of starting in a state digit , accepting 0-9 as input and moving onto state nextdigit on legal input.

the application is difficult because i have to use fsm class only!

yeah...'cause its totally worth doing all that to make a calculator. (ok, so its a learning thing but i'm feeling sarcastic )

i totally agree - its a pointless exercise, this is not even for the programming module, its for CS Concepts!

i still think we should be learning C++

Your not allowed to write it at home with an IDE and then transfer it to your university's LAN?

That's what I did with my projects, when my computer wasn't broken. It's so much better writting with an IDE.. no damned ctrl w to paste, or need to rememeber other funky key sequences just to get around.

I'd recommend getting a trial version of JCreator, http://www.jcreator.com/, especially if you've used MSVC.

I wouldn't be afraid of learning Java. My experience has been that Java is easier to learn than C. Java gives you an awful lot to work with, while C really makes you fight for every inch.

The only thing that I would really think of as a problem with learning Java is that it takes too much to do anything...
That is, in C if you know how to use printf, scanf, and malloc, you can produce just about anything.
In Java, there are too many functions to count, and you will need a reference material in order to use Java.

Just do a forum search for 'Java' and I'm sure you'll find ample reading material on it's merits and failings.
