byte's bite

[gurpreet singh]

Hi
with using left shift operator the result is : -24

byte b =29;
b<<=3;
System.out.println(b);

as this results in overflow becoz some of numerica data shifted to sign bit. But how does this result in -24. If the result is in positve range then after left **** operator it can be calculate as 2's compliment.
like 2*3*29 but it result in 232 which is out of byte range.

Think in binary
29 = 00011101
Shifting it 3 bits left gives : 11101000.
This is a signed value. The left bit begin 1, it means you have a negative number. The positive value is : 00011000, which is 24 in decimal.
So -24.
