question: public static String primitiveTypeLabel ( char typeChar ) { switch ( typeChar ) { case 'B' : return "byte" ; case 'C' : return "char" ; case 'D' : return "double" ; case 'F' : return "float" ; case 'I' : return "int" ; case 'J' : return "long" ; case 'S' : return "short" ; case 'V' : return "void" ; case 'Z' : return "boolean" ; default : System . err . println ( "Unexpected class char " + typeChar ) ; assert false ; return "UNKNOWN" ; } }
target:  Converts a single-character primitive type into its human-readable equivalent.
