[ale] OT, but not as OT as recent stuff (JAVA)

[Mazukna, Thomas]

You can not put primitive types into Hashtable, only objects, so you
probably store Long.

hash.put( key , new Long( 1000 ) );

When you get back an Object form hashtable cast it back to correct type:

Long one = (Long)hash.get(key);
Long two = (Long) hash2.get(key);
long rez = one.longValue() - two.longValue();

or one pass
long rez = ((Long)hash.get(key)).longValue() -
((Long)hash2.get(key)).longValue();

The object is returned by a hashtable.  Basically need to do this:

longvar[0] = hash.get(key) - hash2.get(anotherkey);

The values returned are large numbers (data transfer counts).

I didn't have to buy my radio from a specific company to listen
to FM, why doesn't that apply to the Internet (anymore...)?
