JSON日期格式missunderstanding

Question

我碰到下面的日期格式JSON ExpiryDate": "/Date(-62135510400000+0000)/"

我怎樣才能從中提取日期，並在同一格式的新JSON ???

Answer 1

String json = "Date(-62135510400000+0000)"; 
    String timeString = json.substring(json.indexOf("(") + 1, json.indexOf(")")); 
    String[] timeSegments = timeString.split("\\+"); 
    // May have to handle negative timezones 
    int timeZoneOffSet = Integer.valueOf(timeSegments[1]) * 36000; // (("0100"/100) * 3600 * 1000) 
    long millis = Long.valueOf(timeSegments[0]); 
    Date time = new Date(millis + timeZoneOffSet); 
    System.out.println(time); 

對於日期：

SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy"); 
String dateString = formatter.format(new Date(millis));
