Question: How can in Java I convert this string 23AB to its hexadecimal representation 32334142. Is there any method that can do that easily? Or how could I write this function?

Answer: It is easy indeed:

Use parsing functions form Java API's class Integer...

Integer.parseInt(String s, int radix)
(for hexadecimal radix=16)
and
Integer.toHexString(int i).

It is good idea to add NumberFormatException handling
