    It sounds like you want a Map<String, Char> such as:

    Map<String, Char> map = new HashMap<String, Char>();
map.put("STX", '\u0002');
map.put("ETX", '\u0003');
// etc

    I don’t believe there’s any such map built into the Java standard libraries.

    Converting the Char into a hex string is then a separate step. There are lots of options there, partly depending on which version of Java you’re using.
