java - How to decode to UTF-8 String from Hex encoded string -


html javascript string such as: 
  htmlString = "https \ x3a \"  
   X2f \ x2ftest.com " < / Pre> 
 But I want to explain it as below:  
  str = "https://test.com"   
 This means, I would like a Util API:  
  public static string decodehex (string html string) {// decode and converter here} public static zero main (string ... args) {String html string C = "https \ x3a \ x2f \ x2ftest.com"; string should be str = decodeHex (html string); // str should be "https://test.com"}   
 Does anybody know how to implement this API - decodeHex?   
 
 
 Must be enough I'm implementing  hexadecode  and sorting input incorrectly as an exercise for you.  
  public string decode (string encoded) { StringBinder SB = New stringbilder (); For (int i = 0; i & lt; encoded; langhe (); i ++) {if (encoded.chart at (i) == '\' and & amp; amp; (i + 3) & lt ; Encoded.Length () & amp; Amp; encoded.chart (I + 1) == 'x') {sb.append (hexadecod (encoded. Substring (i + 2, i + 4)); I + = 3; } Other {sb.append (encoded.chart (i)); }} Return sb.toString; }
