Java Generics and numbers

Question

In an attempt to see if I can clean up some of my math code, mostly matrix stuff, I am trying to use some Java Generics. I have the following method:

private <         


        

Answer 1

Java's use of erasure to implement generics means that you're going to have trouble new'ing a generic type.

How about using null to represent 0

retVal[i][j] = null;

You can then assign any type you want to the array later on.
