Retrieve data from Object[]?

Question

In the Debugger I saw that the object receives ['product', 210]

Object obj = prodRepositorio.somaById();

I’d like to get the data on it but it doesn’t work cast or anything.

I’ve tried to

String produto = (String)obj[0];
Long valor = (Long)obj[1];

I already changed it to Object[] but it is in obj[0]
