Fix it with new Byte((int)7). <-- wrong!
Fix it with new Byte((byte)7).
Check the java.lang.Byte class' constructors in the Java API documentation.

Byte class constructor needs byte value as its parameter
so in the above example i passed 7 which is in range of byte value, it still asks for explicit type cast into byte value taking 7 as integer
hope i made my doubt clear
thanks

Hi Aruna,
7 is an integer.
If you want your code to run, it should be declared either as
byte b = 7;
Byte b1 = new Byte(b);
(or)
Byte b = new Byte((byte)7);
hope this helps
Sri

I've just woken up with the thought in my head that something was not quite correct about my post above. Sorry Aruna, that cast should have been to byte and not to int. Thanks to Sri for correcting me.

Barry,
I thought that yours was a typo and now I know it for sure

Yes, it was either not thinking what I was typing, or not typing what I was thinking. But it's getting bad when I wake up in the middle of the night and suddenly had that horrible suspicion I had messed up.
