Before the addition, binary numeric promotion (�5.6.2) is performed on the value 1 and the value of the variable. If necessary, the sum is narrowed by a narrowing primitive conversion (�5.1.3) to the type of the variable before it is stored.

Let me try..
Explicit casting required wherever narrowing conversion is required.
The famous examples,
byte a = 1 ;
byte b = 2 ;
byte c = a + b ; // Error!
int i = 1 ;
byte j = 1 ; // Error WHY WOULD THIS BE AN ERROR?
final int k = 1 ;
byte m = k ; // No Error
I am sure this covers most of it, though it may not be complete.
Feel free to comment/balk/scream/thrash me if I am wrong!!
