Convert Hex To Dec in java with HashMap and put in .txt file...

I'm making a compiler for assembler in JAVA. My program after several processes leaves a text file as follows. 02TLIGHT2.ASM file with this:

CLO
Start:
MOV AL,0 (When a single number exists, a 0 is added before in the conversion to hexadecimal)
OUT 01
MOV AL,FC
OUT 01
JMP Start
END

Im trying by means of my hashmap convert the commands to his assigned hexadecimal value and put it in a text file in the same format?

What i can be doing wrong?

Sample program output i need in 02TLIGHTHexa.ASM file:

FE

DO 00 00   

F1 01

DO 00 FC

F1 01

C0 F6

Explanation / Answer

Solution:

The code has been corrected except a few :

FC, Start these command interpretations are not clear.

Apart from these two the code had a few corrections. The two *null* in the output are the above two.
