Computational Information Geometry Wonderland

I am writing this library for manipulating exponential families, bregman divergences, and so on. I am using Java. Today, I discovered that Java can handle arbitrary number of parameters using the three dots ... syntax as follows:

class VarargsSum
{
    public static double cumul(double... elements)
    {
    double cumul=0.0d;
    for (double el:elements)
        cumul+=el;
    return cumul;   
    }
    
    public static void write(String... records)
    {
    for (String record: records)
      System.out.println(record);
    }
    public static void main(String [] args)
    {
    Double sum=cumul(5.0,4.0,23.0); 
    write("Computational","Information","Geometry",sum.toString());// explicit cast needed
    }   
}

Compiling and running this above code, you will get

Computational
Information
Geometry
32.0

Let me see how to best use this in the library now... Frank.
