JavaCard OS

I want to know how to use javacard.security.Randomdata class.
Could you tell me how to implement the generateData and setseed methods of the RandomData class ? Thanks for any help!

1 Generate one RandomData instance first;
2 Set seed for the instance;
3 Use method GenerateData() to generate random bytes;

For this problem:

You want to implement these two methods?
