I'm sorry but I can not find out where the "wait()" method is declared? Maybe your confusing it with the Thread.yield() method? I don't see much else wrong with your program other than that. Does it compile/run? What output do you get? Regards, cs_student

Can a MOD change the subject of the post for the benefit of others/search engines? Something like 'REVERSE DNS LOOKUP WITH JAVA'? may be more helpful?

So I need to make a long series of if statements on server for checking and respond properly to clients, and separate if statements on client to properly respond to server? Is this the only way of accomplishing this or is there less visually crude method of accomplishing this?

ok it works great now thanks guys. so just for future reference and to make sure i understand, I had to initialize my array within the class, and i need to make a new class that does the returning and reference that. and that was what i was doing wrong

Hello all, Let me explain the outline here first. Basically I want to create a set of JButtons/JLabels for every directory in an array I have. I have the array of directories as Strings, which is fine, but I dont know how to go about creating the buttons in a loop. I have only ever heard of creating components as code, rather than at runtime. This is the code I have, its mostly useless but I figured I would put it in here any way. Code:...

I've posted this here in the Java section merely because someone told me that Java is what is used for my main question. So here it is. I am a beginner, all I really have experience with is python, so please keep that in mind if answering.

I was told that this is possible using Java, but I have no idea on...
