A:
Use SimpleDateFormat to convert between a date string and a real Date object. with a Date as starting point, you can easily apply formatting based on various patterns as definied in the javadoc of the SimpleDateFormat (click the blue code link for the Javadoc).
Here's a kickoff example:
String originalString = "2010-07-14 09:00:02";
Date date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse(originalString);
String newString = new SimpleDateFormat("H:mm").format(date); // 9:00

You can construct a new `Date` object with timestamp in milliseconds and then just format it. If you're actually retrieving it from DB, you should use `ResultSet#getTimestamp()` to get a `Date` as answered in [one of your previous questions](http://stackoverflow.com/questions/3473421/). Or even better, make use of the SQL builtin date/time functions to return the timestamp already in the desired format so that there's no need for the expensive task of remassaging the data of every row afterwards in Java. In that case, just get the hour by `ResultSet#getString()`. Use the right tool for the job

i am getting it from the database.but needed to generate a print report. so thought i could iterate on the values and change them on the fly.as i need to just print it out in the end. unable to get it done in any starightforward way :(

A:
I'm assuming your first string is an actual Date object, please correct me if I'm wrong. If so, use the SimpleDateFormat object: http://download.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html. The format string "h:mm" should take care of it.

Even if the String is *not* a `Date` object initially, you can use `SimpleDateFormat.parse()` to turn it into one, as per BalusC's example.

Indeed, without AM/PM marker (`a`), you'd rather prefer `H` above `h` to avoid ambiguity between 9:00 (AM) and 9:00 (PM).

A:
Date date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2010-07-14 09:00:02");
String time = new SimpleDateFormat("H:mm").format(date);
