Writing a string to file as a byte in Java

Question

I'm having a little trouble writing the values I want to a file. I'm using RandomAccessFile to output the values. What I want to do is take a string (which contains two digits, 0-9) and write them to a file as a byte. I've tried a few different ways but cannot seem to nail it.. Any help?

Answer 1

 String yourString = "0F"; 
 byte aByte = Byte.parseByte(yourString, 16);

And then just write that byte in your file and you are all set.

NOTE: That 16 is the radix, use 10 for decimal, 16 for hex
