System.out.print(i + "HEX VALUE IS :"+hexVal); // String to Hex

int intVal = Integer.parseInt(hexVal, 16);
char charVal = (char) intVal;
System.out.print("...ASCII(String) Value : "+charVal);
}
}
}
}

Do you, or anyone else, see room for improvement??

I plan on adding functionality to make all the input from a file and
all output to a file. I may need console output to give display of
steps.

Thanks.

The big thing I can see is that you shouldn't use the word "Ascii", when what you're really doing is looking at the UTF-16 values, not Ascii.

I would also replace your hexVal creation with something that will pad zeros instead of just adding two zeros before it.
