Convert String MM/dd/yyyy hh:mm:ss to Milliseconds in Java

Asked by: rkneal

I need to know if there is a way to convert a string in MM/dd/yyyy hh:mm:ss format to its equivalent in milliseconds (Epoch time) in Java?  I have a string in this format that I need to convert to milliseconds so I can send the converted value through my program that requires the time to be in this format.  Any help would be appreciated.

You can use SimpleDateFormat to parse and get the epoach

String text = ... // Date text
Date date = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss").parse(text);
long epoach = date.getTime();

Use the class SimpleDateFormat.

String date = "......";
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss");
Date d = format.parse(date);
long time = d.getTime();

I was able to resolve my issue by using the following try...catch block.  I attempt to parse the string as a long and if that fails then parse the string as a date.

 Date localDate = new Date();
        try
        {
          localDate.setTime(Long.parseLong(paramString));
        }
        catch (NumberFormatException localNumberFormatException)
        {
          localDate.setTime(Date.parse(paramString));
        }
