JavaML - How to add separators when exporting data as CSV?

Question

I am trying to generate random instances to create a dataset.I try creating it with the next code:

....
Instance tmpInstance = InstanceTools.randomInstance(4);
data.add(tmpInstance);
....

If I print it in the system.out:

[{[0.9539317274046737, 0.7367254963392549, 0.9265618402925881, 0.6691294511669751];null}]

But when I save it to a file, the numbers aren't separated by anything, they are all the numbers together.

net.sf.javaml.tools.data.FileHandler.exportDataset(data, new File("C:/Users/agomez/Desktop/data.csv"));

How can I separate them?

What is this `InstanceTools`, could you provide full package name? — Oleg Cherednik, Dec 01 '17 at 07:26

The javaml Filehandler you use does not provide that option. It is specified here:

If you need CSV output, follow questions like these:

Basically commons-csv or opencsv. But if it's really only numbers, you can probably write your java code.

And what library I could use to create dataset that allows comma separated values? – Asier Gomez Dec 01 '17 at 08:22
