Storing Hexa-decimal Values

I have an sequence of 30 or so hexa decimal values 0x01, 0x02... My question is how can i store these values in Java. I do not know if it matters to convert it into String and store it. But thats what i am not looking for. I just want to store the hexa decimal as constant data. Please also consider the contents representing the Hex-Decimal form and if/what happens to it ?

Hexadecimal is just a format to display numbers, just like decimal, binary or octal. Numbers are just numbers - hexadecimal is not a property of the numbers themselves, it's only a way to display numbers.

Writing the numbers as 0x01, 0x02, etc. in your source code is exactly the same as writing them in decimal 1, 2 etc.

So, you can store the numbers like you would store any other numbers - for example as an array of ints.

Just store them in an integer (if it fits within the value range) ... when displaying them, convert it as hex.

You should store them as Integers using the Integer.valueOf(String s, int radix) method.

In your case, the radix is 16.
