Peculiar fruits in the JDK

[Ulf Zibis]

Hi David,

can you show an example using a 'switch' statement which is shorter or 
faster than:

            char c = c2bMap.charAt(c2bMapIndex[(current & MASK1) >> 
SHIFT] + (current & MASK2));

or more faster for special mappings:

            char c = (current < '\u0100') ? c2bMap.charAt(current) :
                c2bMap.charAt(c2bMapIndex[(current & MASK1) >> SHIFT] + 
(current & MASK2));

Regards,
Ulf
