I have a Java project where I must use a generic data structure. I was thinking of using ArrayList- but I have no idea what kind of class I should write. In the past I ve done simple bank account systems and song libraries- but I m looking for something different. Any ideas?

I just got some Petite Anubias and Some Philippine Java Ferns that I ordered online- they have leaves on them and I am attaching them to rocks with cotton string should I just rinse them and add then to my tank or shoudl I remove leaves?
when I opened the package the Petite Anubias leaves were slimy and fell off.. are they still ok ?

Sometimes when I am playing music using Media Player- my computer will slow right down- and the music will be skippy and choppy. My computer will often be unresponsive until the song has finished playing- after which it speeds up again. It doesn t happen way too often- but it is annoying nonetheless. It also happens more often when I am using flash/java/shockwave apps. Any ideas to why this is happening? Thanks! :D
I have used Microsoft s RAM Testing Utility. According to the complete/extended test- my RAM is fine- and it is not a hardware problem. Is this maybe an issue of not having enough RAM (currently 512MB on WinXP). I have also heard that Celeron processors are not the best processors in the world- so could this be a problem as well? Thanks again! :D

Hi!

I m working on a java based chat program. It has a server and a client. The server and client communicate through sockets. The thing is- that if I put the server behind a proxy server- the client can t reach it...
I m sure it s not a firewall issue and it s not about sockets being already bound.
And besides these- I don t know how to verify if the server is actually behind a proxy or not...
If you can- please post or e-mail a simple example for a server- that works behind a proxy server!
Please help! :-)

Thanks in advance!
To Colanth:

There is absolutely no firewall involved... No windows firewall- no ZoneAlarm- nothing.

The server is simply behind a proxy server.
