I believe enum have a  name   in its API  pretty simple to use like this example   private int security  public String security    return Security values   security  name      public void setSecurity int security   this security   security         private enum Security               low              high         With this you can simply call   yourObject security      and it returns high low as String  in this example

You can add this method to your Status enum    public static String getStringValueFromInt int i         for  Status status   Status values               if  status getValue      i                 return status toString                              throw an IllegalArgumentException or return null      throw new IllegalArgumentException  the given number doesn t match any Status         public static void main String   args        System out println Status getStringValueFromInt 1       OUTPUT  START

You can use values   method   For instance Status values   0  will return PAUSE in your case  if you print it  toString   will be called and  PAUSE  will be printed
