No please... not again another discussion about Erlang vs. Java. Is it 
only a matter of soft real-time abilities and hot code loading?
No! These are only minor reasons, I think. The best comparison I show to 
my student is a piece of code that filters data in a vector:

Java:

   Vector<int> source = ....;
   Vector<int> dest = new Vector ();
   for (int i = 0; i < source.size(); i++) {
     int data = source.elementAt (i);
     if (data > 10) {
       dest.add (data);
     }
   }

... and the code is worse if a "int[]" has to be filtered, instead of a 
"Vector".

Erlang:
   [ X || X <- Source, X > 10]

This should *definitively* remove any doubts :-))
