byte shift

[Susmita Pal]

byte a=12;
a=(byte) (a<<5)
=(byte)(0000 0000 0000 0000 0000 0000 0000 1100 <<5 )
=(byte) 0000 0000 0000 0000 0000 0001 1000 0000
=1000 0000 // cause it is byte

so the answer I get is 128
how do I get -128.
It will be great if any body can help me
Thanks in adv.

Hi Susmita,
Java uses two's complement arithmetic which means the left-most bit represents the sign: 0 for positive, 1 for negative.
Check out Cat and Mouse Games with Bits for more info.
Hope that helps.
