converting hexadecimal to string

[chirpyform]

Has anyone got any code to convert a string of hexadecimal to a string normal.

Ex

3c -> 60 -> '<'

in this case I pass "3c" and I would like "<" returned to me


Thanks Chris

This is from a HEX editor I wrote. I have a binary file ("in") that I read in and display 16 bytes per line:

		int nbytread=in.read(datain,0,sz);
		String datast = new String(datain);
		for (int i=0; i<numlines; i++) {
			valst="";
			bi = 0;
			for (int j=offset+(i*16);j<offset+(i*16)+16;j++) {
				tempst=Integer.toHexString(datain[j]);
				val1 = tempst.length()-2;
				if (val1<0) {
					val1=0;
					tempst="0"+tempst;
				}
				valst=valst+tempst.substring(val1);
				valb[B][I]=datain[j];
				bi++;
			}
			tempst=datast.substring(i*16,i*16+16);
			String badd = String.valueOf(offset+i*16);
			while (badd.length()<5) {
				badd = badd+" ";
			}
			lst1.add(badd+" "+valst+"     :"+tempst);
		}

Or something like:

public class Test {

    public static void main(String[] args) throws Exception {
        String hex = args[0];
        char character = convert(hex);
        System.out.println(hex+" = "+character);
    }

    public static char convert(String hex) throws Exception {
        return (char) Integer.parseInt(hex, 16);
    }
}
