I see a wonderful mix of hard programs here. :) My hardest would have to be work on creating a low-level type-safe language similar in spirit, but more expressive and powerful than Microsoft's [URL=http://research.microsoft.com/vault/]Vault[/URL] Language. The key to this language was that you could annotate code with a set of …

Well I'm sure that i_me_roo probably has a main and extra bracket at the end. The compiler complaint was about return statements. i_me_roo if you look at the code, you'll see that it is possible to go straight through the function without hitting the return statement. This is what the …

What's the point of downloading the source code? you aren't going to present an extension to the IDEs are you? The source code for any of those projects will be mammoths if you are new to Java and/or have no software engineering project experience. Ed [QUOTE=RaySan]I am a newbie on …

The best way to obtain IP address is via the JDK's InetAddress http://java.sun.com/j2se/1.4.2/docs/api/java/net/InetAddress.html#getLocalHost() This returns InetAddress which has many goodies you can play around with. For example, You can do things like reverse domain name loook ups on arbitrary ipaddresses... or ip addresses from hostnames.

This is absolutely not true! I haven't done bluetooth in C# before, but I've done it in C/C++ and am familiar with the bluetooth protocol. You need to just do a device inquiry over sdp (Service Discovery Protocol). This is not vendor specific---A Huge Nightmare if it was vendor specific!!! …

Hey sani, Have you used eclipse before? I wonder if you could leverage some of their plugin loading code. That would be awesome. You could write your own plugin loading code rather easily. Have a plugin directory that your app will scan for plugins. Plugins can essentially be packaged java …

Definitely look into using Eclipse [URL=http://eclipse.org]http://eclipse.org[/URL] . I eschewed IDEs for a long time. I've tried all the commercial IDEs and disliked them.

An alternative solution, I've used to as a cheap profiling trick in big programs: long startTime = System.currentTimeMillis(); // time at start in millisecs // //code // long stopTime = System.currentTimeMillis(); // time at end // time elapsed is stopTime-startTime See this link for details. http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html#currentTimeMillis()

To implement an interface (in this case ActionListener or ItemListener), you must write all the functions that the interface provides. One such function you're missing is actionPerformed(ActionEvent). If you put this function into your ChatClientApplication class, it will stop complaining.
