How to escape HTML special characters in Java?

Question

Is there a way to convert a string to a string that will display properly in a web document? For example, changing the string

\"\"

Answer 1

Better do it yourself, if you know the logic behind - it is easy:

 public class ConvertToHTMLcode {
        public static void main(String[] args) throws IOException {
          String specialSymbols = "ễ%ß Straße";
          System.out.println(convertToHTMLCodes(specialSymbols)); //ễ%ß
   }

   public static String convertToHTMLCodes(String str) throws IOException {
      StringBuilder sb = new StringBuilder();
      int len = str.length();
      for(int i = 0; i < len; ++i) {
          char c = str.charAt(i);
         if (c > 127) {
            sb.append("&#");
            sb.append(Integer.toString(c, 10));
            sb.append(";");
        } else {
            sb.append(c);
        }
     }
       return sb.toString();
   }
}
