java is case sensitive. but while representing hexadecimal numbers both upper case and lower case letters allowed. how it is possible?

Are you going to say you think it should be programmed to accept only 0xffff or 0XFFFF and not both? You can program a lexer to be case sensitive or case insensitive, or even to change case. So you can have OxFfFf, just as you can declare a float literal as 12.345f or 12.345F.
