Core Java. What output will be and why ?
int x = (int) (char) (byte) -1;
System.out.println(x);Could you explain step by step what happen here and why ? thanks you in advance !
byte in Java is signed 8-bit twos' complement - so the -1 as a byte is eight 1s , ie. 11111111.
the char and int casts are meaningless, so you end up with an int (which in Java is 32-bit signed two's complement, giving the positive decimal result of 65535.
Is that what you meant to ask?

Thx everybody !
-1 --> Byte (1) --> Char (Some Weird Character) -- > Int --- > 65535.
-1 --> Byte -- > -1
-1 --> Char --> 'ï¿¿'
'ï¿¿' --> Int - > 65535
