decimal value for "ffff" is 69904

[Siva kandasamy]

Hi there,
Please look at the code.
If I uncomment at variable "d", I do get compilation error.
Can you tell me why ?
My understanding is, decimal value for "ffff" is 69904.
Therefor I don't see any difference between variable c and d.
Please forgive my ignorance.

      
class Test {
        public static void main(String agrgs[]){
        char c = 0xffff; // max char hex value
        //char d = 69904; // max char hex value
        char e = 100; // max char hex value
        }
}
 

thanks

0xFFFF is 65535, not 69904. 69904 is thus somewhat larger than the largest possible char value -- hence the compile error.

0xffff == 65535 == Character.MAX_VALUE
Decimal value of a hex number can be found by adding the product of each hex digit multiplied by 16^(position), as such:

0xABCD == ?
(A*16^3) + (B*16^2) + (C*16^1) + (D*16^0) == ?
(10*4096) + (11*256) + (12*16) + (13*1) == ?
40960 + 2816 + 192 + 13 == 43981
