int to byte conversion/casting

Answer Choices:
- Compilation Error
- Compile and print 100
- Throw a runtime exception
My answer to this was (Compilation error), as Im trying to assign a 32 bit int to an 8 bit byte, hence loss of precision. However the compiler doesnt complain and instead compiles fine and prints out 100. If i remove the final from int i = 100; declaration and the rest of the code remains the same i do get a compilation error.
Comments? Thoughts?

This code compiles fine and output is 100
Here final int i is a compile time constant. You don't have any casting problem. If you remove final from 'final int i' you would get possible loss of precision error. The answer is 'Compile and print 100'.

On the same topic:

will compile and print 30
although here the compiler will balk at line 3 because of possible loss of precision:
