Not really a syntax question per-se, but is it possible to use pointers in processing?

processing being based on java does not have pointers. but objects are passed by reference and that's pretty close to pointers from my perspective ...

Like fjen says, all objects are actually references anyway.

So when you declare

MyClass myInstance;

myInstance is actually a pointer to MyClass - hence the need to do myInstance = new MyClass(...) before using it.

If you need a pointer to int, char etc you can use the syntax

int []myInts;
You dont get the same low-level memory control as you would in C, but you can pass it to functions etc...

This is all standard Java stuff and not specific to Processing.
