Hi there.
I do not know of any class or method that will do that for you
automatically. I have included a small example that will do that for you. I
think it is quite optimized for speed, but I bet it could be more improved.
try {
String hexStr = "546F6F6C73206F6620746865205472616465"; //your original
string
int hexLength = hexStr.length();
char[] converted = new char[hexLength/2];
for(int i=2; i-1<hexLength; i+=2) {
converted[i/2-1]=(char)Integer.parseInt(hexStr.substring(i-2, i),16);
}
String convStr = new String(converted); //your converted string
} catch (Exception e) {
System.out.println("error in hex-to-string conversion.");
}
try this, and good luck.
PS. If someone out there sees a bug in that code-snippet, or have a
suggestion that could improve performance, send me a mail.
