Java output from (y++z / (z-- -6.0) + 'd'0.5);

double x = 4.0;
long y = 10;
byte z = 8;
char c = 'd';

System.out.println (y*++z / (z-- -6.0) + 'd'*0.5);

The result is 80.0, but I don't know why?

d is ASCII-Code Number 100.
First term is 80 second term is 2 third term is 50 ?

Solution

First term is 30, second is 50. Totals to 80.

'd' = 100

100 * 0.5 = 50

++z = 9

y * ++z = 10 * 9 = 90

z-- = 8, but after the operation. In the operation it is still 9

z-- - 6.0 = 9 - 6 = 3

90 / 3 = 30

30 + 50 = 80

Java output from (y*++z / (z-- -6.0) + 'd'*0.5);
