Re: Peculiar fruits in the JDK

Also I've found out, that MASK1 is superfluous, because on implicit 
converting from char to int all upper bits are automaticlly 0. So we can 
code instead:

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

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

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));
