Do you run it using IDE like Eclipse?
You could check how the code executes using debug mode.

The main consideration is the lack of break statements. That means that if roman == Roman.X three switch statements will be executed:
- roman = Roman.C;
- if(roman.ordinal>2)z+=5;
- x++

Now just loop through the code; I suggest you do it manually. Like this:
- start: x == 7, z == 2, roman == X
- iteration 1: roman == X so roman = C, z += 5, x++, and another z++. At the end, x == 8, z == 8 and roman == C
- iteration 2: ...

Renamed your Roman variable because the forum won't let me use its name outside code blocks.

And the code as it is, can't compile...

HINT: Error is in line 14 (maybe just a small typo)
