java - Converting long (whose decimal representation represents a yyyyMMdd.. date) to a different date format

Question

I have long of the form

20120720162145
yyyymmddhhmmss

I have to convert it to 2012-07-20 4:21 PM form. Is there any way in Java to do this using Date?

Answer 1

Here's how:

long input = 20120720162145L;

DateFormat inputDF = new SimpleDateFormat("yyyyMMddHHmmss");
DateFormat outputDF = new SimpleDateFormat("yyyy-MM-dd K:mm a");

Date date = inputDF.parse(""+input);

System.out.println(outputDF.format(date));

Output:

2012-07-20 4:21 PM
