I hope this isn't too much of a stupid question, I have looked on 5 different pages of Google results but haven't been able to find anything on this.
What I need to do is convert a string that contains all Hex characters into ASCII for example
String fileName =
75546f7272656e745c436f6d706c657465645c6e667375635f6f73745f62795f6d757374616e675c50656e64756c756d2d392c303030204d696c65732e6d7033006d7033006d7033004472756d202620426173730050656e64756c756d00496e2053696c69636f00496e2053696c69636f2a3b2a0050656e64756c756d0050656e64756c756d496e2053696c69636f303038004472756d2026204261737350656e64756c756d496e2053696c69636f30303800392c303030204d696c6573203c4d757374616e673e50656e64756c756d496e2053696c69636f3030380050656e64756c756d50656e64756c756d496e2053696c69636f303038004d50330000
Every way I have seen makes it seems like you have to put it into an array first. Is there no way to loop through each two and convert them?

Just use a for loop to go through each couple of characters in the string, convert them to a character and then whack the character on the end of a string builder:
Or (Java 8+) if you're feeling particularly uncouth, use the infamous "fixed width string split" hack to enable you to do a one-liner with streams instead:
Either way, this gives a few lines starting with the following:
Hmmm... :-)
