Creating an n-dimension Array in Java during runtime

Question

I have a String which contains arrays. Example:

\"[[1, 2], [4, 5], [7, 8]]\"

Now, I want to make an actual Java array out of this. I have c

Answer 1

If you are doing numeric work then you should probably use a library. For example my open source library Vectorz provides proper support for multidimensional arrays / matrices (with doubles).

Then you can just do something like:

INDArray m=Arrayz.parse("[[1, 2], [4, 5], [7, 8]]");

The INDArray object encapsulates all the multidimensionality so you don't need to worry about writing big nested loops all the time, plus it provides a lot of other functions and capabilities that normal Java arrays don't have.
