-s java : 디컴파일된 파일의 확장자를 java로 지정

-8  : 유니코드를 8 bit 스트링형으로 변환
 (jad -o -r -8 -sjava -dsrc .\*.class)

-r       - restore package directory structrure
-radix<num> - display integers using the specified radix (8, 10 or 16)
-s <ext> - output file extension (by default '.jad')
-safe    - generate additional casts to disambiguate methods/fields (default: off)
-space   - output space between keyword (if/for/while/etc) and expression (default: off)
