Hey Grady,
If u check line 1...
return c1;
an implicit cast is put there 2 convert char to byte.
this is because c1 is a compile time constant...
(its value is known at complie time ie final char c1='\u001')
but in the case of line 2...
there is a problem cause c2 is not a compile time constant...
it is a definately a constant, but its value is not known at
compile time.. as it is an argument to a method its value can
change therefore the compiler complains at line 2.
