Answer / nirmala
If the specified value exceeds the range that will result
overflow.
similarly,
if the specified value below the range that will result in
underflow
ie
byte b=259;(butits rangeis(-127 to 128) totally 256
in this u will get overflow error.

the operation.

Answer / ramesh kumar
byte b = (byte)250;
Here I assinged the value to b more than the positive range
of byte. So, It leads to overflow and we won't get any
error in compile time or run time.
But some unexpected value will be stored into b. i.e b = -
6. This will affect your logic.
