I have been looking and it seems tahat java does not have operation overloading. Which methods do we want to have here?

We could add methods like arrayj.plus(arrayj2), arrayj.pow(2)...
Do you think that would be useful or people would default to the kernels?

For now I would say simple a debug / print function would be great.
Not urgent for now, other issue are more important.
