"Ciao" (Hi) to everyone,
please can you tell me how can I sort an ArrayList<K> of generic
types ?

If this arraylist were of this kind, ArrayList<String>, I could sort
it simply using this instruction:

ArrayList<String> list = new ArrayList<String>();
java.util.Collections.sort ( list );

but, in my case, i see that i cannot sort in this same way when i use
an arraylist of generic types.. like this one:

ArrayList<K> list = new ArrayList<K>();
/* ERROR --> */ java.util.Collections.sort ( list );
