It solved the first part of my question. i do not know how to create a
vector.
I tried e.g.:
Vector probabilities = new Vector();
//to then set the values like:
probabilities.set((double) 0.1);
probabilities.set((double) 0.2);
probabilities.set((double) 0.3);
probabilities.set((double) 0.4);
But eclipse shows an error (but does not say what is wrong). I do not
know how to use interfaces. Obviously I can't use it as if it was a class.
Should be easy,... somehow.

I'm sorry it's actually me that is wrong. UncommonDistributions is a
Mahout class. I made the wrong assumption based on the name and the
fact that you seemed to be talking about java.util.Vector. The
"Vector" here is Mahout's class.
So does Isabel's answer solve your problem? You get a Vector with all
the values you want back. You simply access with get() methods.

there is no multinomial random number generator in UncommonsMath -
unfortonately. there is also no hypergeometric random number generator. I
thought it would be much easier to use an existing one, than write an own
one.
And once i know how to use the Vector interface, i might be ablie to use the
one provided by mahout. for the hypergeometric thing I might have to write
an own function,... (there should be a package providing those functions -
I'm wondering why there isn't one,...)

It seems like you're not really using Mahout, but a library that
Mahout uses -- Uncommons Math. See
https://uncommons-maths.dev.java.net/ . I think this is the library,
and documentation, you really need. Everything you refer to are not
Mahout APIs.

I did not realize that the methods are static methods (Thats why i tried
to
use a constructor).
But how do I set up the vector with my probabilities?
And do I have to set a seed? which ones can I use?
Why is Vector used for the Method, and not ArrayList/LinkedList?
Thanks four your help.
