Following me everywhere? why do I get those exceptions very much??? why are they raised?? My classes are always in the same package as the class they accesses them.. I know they are there. Why doesn't the compiler find them????

thanks for your help ppl...please help :@

don't know, you're not giving us much to go on ..
sure you used the right names and they're all compiled?

these is one of the classes that give me that exception when i debug it...ClassNotFound..... it doesn't even leave my driver class...LinkedListQueueDriver .. please tell me what i am doing wrong!:(

could you give the entire exception message? what class doesn't he find, ...
also, in your previous post, it looks like you have all your classes in one file, you might want to edit that into three code blocks to make it easier to read

i do not get any messege when i run it. It just does not do anything. Its when i debug it (using the debugger) that i see its the 'ClassNotFoundException<Throwable> ....I dont knw what it wrong, cause its happening a lot more often..
The three classes are in three files...if there is any way i can make it better here , it would be nice if u let me know how i can do it cause i thought i was doing it right :):)... thanks again
