View 2 Replies View RelatedProgramming :: Stick With Java?
May 12, 2011Situation: this semester I took an class called Introduction to Software Design with Java.It was my first intro to programming. The class had a very odd structure:1. The text was extremely high level. The first few chapters were all about object oriented programming, how objects interact, all about specification, etc (without ever talking about implementation).2. The lecture simply followed (directly) the text. And as a result was rather uninteresting.3. While highly theoretical (in that it was very high level approach), we never talked about how the computer was dealing with the information, etc.as all very "hand waving/magic" approach.
Okay so enough of the complaints:Question: This summer I'd like to dive a bit more into a language mainly out of frustration and lack of a good book. I'm thinking perhaps a lower level language.1. Would C++ be a good second language? Or should I give Java more time?2. If I am going to go with something else, is C++ sufficiently different, or should I go with C

Programming :: How To Set Up Global Class In JAVA?
May 10, 2011I've had to do some code in java, a language I'm very much unfamiliarly with so please excuse my incorrect use of terms. The basic outline of my problem is I create a class object as a local within a swing button function it works fine. If I create it as a global ( with I think I need to do ) within main, then prototype it with the other swing objects at the bottom of the file when it is called it causes a host of problems. I think the easiest way is to show it.

Feb 26, 2011I'm currently writing a program which will eventually send two 2d arrays to another machine using UDP, and then back again.
To do this I'm converting to a byte array which as far as I'm aware is the only way possible. I'm sure the problem is on the receiving program which receives like this:
Code:
DatagramSocket socket = new DatagramSocket(2000);
DatagramPacket packet = new DatagramPacket(new byte[5000] , 5000);
socket.receive(packet);
