how to get date from 12 hour format to 24 hour format in android

hello I have date like..

String date="09:00 AM"

But I need 09:00:00

So I use following.

 String date="09:00 AM"  
 SimpleDateFormat f1 = new SimpleDateFormat("hh:mm:ss");
 Date d1= f1.parse(date);

But it give me parse exception.

Please help me to find this.

Thanks in advance.

That's not the correct format for parsing that date, you need something like:

"hh:mm a"

Once you have a date object, you can then use a different format to output it. The following code segment shows how:

import java.text.SimpleDateFormat;
import java.util.Date;

String date = "09:27 PM";

SimpleDateFormat h_mm_a   = new SimpleDateFormat("h:mm a");
SimpleDateFormat hh_mm_ss = new SimpleDateFormat("HH:mm:ss");

try {
    Date d1 = h_mm_a.parse(date);
    System.out.println (hh_mm_ss.format(d1));
} catch (Exception e) {
    e.printStackTrace();
}

This outputs:

21:27:00

as you would expect.
