| Well basically I went into the CP11 class because I wanted to do C++. So all through the semester, I'm waiting excitedly to take a C++ class. The teacher said that we most likely would be doing C++. At the last minute, everything goes wrong. Turns out we're doing Java. All I know about it is that it runs REALLY slow on my computer and isnt for people who want to make programs that will run very quickly and efficiently. Can anyone give me some more on what to expect for the course? | |||

| Well, one usually takes Java before they take C/C++; I doubt you'll do Java the entire time. | |||

| be glad your school offers more then just qbasic... plus if you want to C++ that bad just find some tutorials... | |||

| as for slow--java is mostly for server or cross platform applications. using to write a CPU demanding game is usually out of the question but there is a debate between C vs. Java so yeah. To me, they are equally as fast with computers today. But C is more efficient since it compiles to CPU code while Java must run through an interpreter. Slowness also is influenced by computer make up--Java runs just fine for me but if the HD is going constantly then well, it is almost impossible to run. Anyways, Java (to me) is the best way to learn Object Oriented Programming. C++ has nasty syntax that doesn't make it kind to OOP learning. (edited by neotransotaku on 02-08-05 07:53 AM) |

| Once you learn Java, it shouldn't be too hard to learn C++. In fact, once you learn any object orientated programming language, it's not hard to learn another one. | |||

| What dan said is true. I couldn't program any of Java, Objective-C and C# two years ago. Can now. | |||

Ugh, this same thing happened to me. They mentioned C but we ended up with Java and Turing instead.  But the next year, we did VB6.  I don't think my mark ever dropped below 90 that year. The teacher would look at my code and just walk off confused, it rocked. |

| My school did the same thing with our Computer Science class. However, it has turned out to be a blessing, as Java is really bloody spiffy. Java does all the object oriented types of things very well, and it has a metric crapload of useful classes to help out. Also- Originally posted by neotransotakuPshaw to that. I've been programming a game in Java. http://squashmonster.tripod.com/Treasure/treasureGameSSA.png http://squashmonster.tripod.com/Treasure/treasureGameSSD.png 3D graphics are usually considered to be CPU demanding, but I've not dropped below 60fps yet. You could compare VB to assembly for all it matters -- the way you program it matters a lot more than the innefficiency of nearly any programming language (unless you're using something intentionally lousy like Whenever or whatever the one I'm thinking of was called). Say Java took 1.5 seconds for what C++ did in 1 (that's way overkill, I'm sure). Now say you have a generic RTS with two sides, with n units on each side trying to find the nearest enemy. That's 2n^2 times through some logic in a for loop with the most obvious way of programming it. If you quickly made a grid and put the ID of each unit at its location, however, you would have to go through some logic 2n times. If you had 10 units on each side, that's 200 vs 20. That's 10 times, not 1.5 -- in almost every case, the difference in efficiency between any two languages is negligable. |

| a very simple example: when calculating 2^100 you can do it with a loop - simply mulitplying with 2 100 times. well needless to say this way sucks unless your exponents are very small. 100 mod 2 = 0 so we can do 2^100 = (2*2)^50 = (4*4)^25 = 16^24 * 16 = (256^12)*16 = 65536^6 * 16 = ... simply checking if the exponent is odd or even does the trick so if you program algoritm 1 in c and 2 in basic the basic version will be faster for big exponents. of course if you're positive all your algorithms are great you can go ahead and kill overhead by using c or even asm. of course this is just an example - you normally use very optimized standart libs for something like this. |

Originally posted by neotransotaku sure, if you're retarded  . if you're anywhere close to a half-decent programer there really isn't much that should throw you for a loop in C++. it's a fairly straight-forward syntax, even if used for an introductory language (which i'd actually recommend). and personally, as far as java is concerned, i feel that limiting the programmer to one, and only one code structure is pretty fucking retarded.(edited by Gavin on 03-18-05 12:04 AM) |

Originally posted by GavinI know I am, you don't have to remind me Originally posted by GavinYeah, the syntax is straightforward enough for introduction. But when you start using the more advance stuff of friends, virtual, and company it becomes confusing to learn. The same stuff I can do in Java can be done in C++ but it seems a pain to do so. Java has one code structure...then what kind of code structures does C++ have? |

| it's a pain to do java stuff in c++? eh? no. the whole cpp is hard stuff is just a myth it's not that hard. all these crappy apis are the hard part but c++ it'self isn't. (edited by loadingNOW on 03-18-05 01:51 PM) |

| If you're interested in doing Managed C++ (.NET) then take the Java class. The C++ will be so easy to learn once you know Java, you'll be able to teach yourself everything you need to know within a few days. | |||

Originally posted by loadingNOWAPIs are fun because there is no point in re-inventing the wheel although, it's a pain to work with Object  anyways, it's just preference--there are certain things in Java I dont' need to worry about in C/C++ and vice versa. That is why it's easier for me to develop in Java because of technical errors I didn't account for in C/C++... oh well, program the way you want and I'll program my way |
