I had generate a 256 bits random keys into a file.
The plan is to using the 256 bits random key as a source to generate a RSA (public and private) key.
Anyone kind soul know how I can do it?

I think you can generate keys using KeyPairGenerator, which can be initialized with SecureRandom.
SecureRandomhas constructor which takes array of bytes as seed.
