Answer 1

When implementing switches many optimisations can be made for performance, otherwise you have to list through all the switches till it matches.

What I would do here, is have a main set of switches for the first character then nested switches inside, therefore if the choice was z it doesn't have to loop check every name first

switch(FIRSTCHAR){
case A: switch(index){
        case 0: ..... break;
        etc

        }
break;

case B://do the same
}

Another way is to break your switch statement up into smaller equal sized statements. This is faster due the way the bytecode is compiled (ref Java performance tuning - shirazi)
