nullpointerexceptions

Posted by matt on December 08, 2001 at 4:20 PM

I am coming from a C++ backround but haven't programmed in a few years. I am repeatedly making the same mistake and I think its due to a general error in how I'm trying to solve things. I keep getting nullpointer exception when I try to create an array of class objects. This also happens when I try to use methods from another class. I have read Java in a Nutshell. I'm not sure I can make my problem any clearer right now because I've been staring at it and fiddling with it so long I don't know what is going on anymore. Can anyone point me to a simplest case scenario of object oriented class use in java? Thanks and sorry to just jump in with a general question like this.
