Which of the following are valid declarations?

b) char c= "cafe"
c) char c= '\ucafe'
d) char c= '\u01001'
e) char c= '0x001'

Hades,
Jennifer is quite right. Please take some time to read Valentin's recently posted suggestions about making good use of this forum.
Thanks,
Junilu

(a) and (c) represent valid character literals.
(b) "cafe" is obviously a String Literal
(d) and (e) do not conform to the following:-
UnicodeInputCharacter:
UnicodeEscape
RawInputCharacter
UnicodeEscape:
\ UnicodeMarker HexDigit HexDigit HexDigit HexDigit
UnicodeMarker:
u
UnicodeMarker u
RawInputCharacter:
any Unicode character
HexDigit: one of
0 1 2 3 4 5 6 7 8 9 a b c d e f A B C D E F

Have a look at the JLS for more info.

I don't think so it is nonsense on forum
