Simple way to turn string to hex

Question

Hello...
I was wondering if there would be nice way to get string, rather long one I might add, to hex form for mobile phone purposes... Preferably to string if possible.
I have looked through forums and have tried to find a nice solution but can't.

To Hex String:
final String nonHexString = "Hello from YoGee";
System.out.print("0x");
for (int i = 0; i < nonHexString.length(); i++) {               
  System.out.print(Integer.toHexString(nonHexString.charAt(i)));
}Back again:
final String hexString = "0x48656c6c6f2066726f6d20596f476565";
int length = hexString.length();
String[] temp = new String[(length - 2) / 2];
int counter = 2;               
for(int i = 1; i < ((length - 2) / 2) +1; i++){
  temp[i-1]= hexString.substring(counter,counter+2);
  counter = counter + 2;
char[] chars = new char[temp.length];
for(int i = 0; i < temp.length; i++){
  chars[i] = (char) Integer.parseInt(temp, 16);
System.out.println(new String(chars));
