convert string to date and time as am/pm format [duplicate]

Question

 string : 2014-04-25 17:03:13

using SimpleDateFormat is enough to format? or otherwise i will shift to any new API?

Date date = new Date(string);
DateFormat dateFormat = new SimpleDateFormat ("yyyy-MM-dd");
out.println( dateFormat.format (date));

My expected result is (India zone):

Date : 25-04-2014
Time : 05:03 PM

Answer 1

Remembering that Date objects have no inherent format, you need two DateFormat objects to produce the result you seek - one to parse and another to format:

String input = "2014-04-25 17:03:13";
DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
DateFormat outputFormat = new SimpleDateFormat("'Date : 'dd-MM-yyyy\n'Time : 'KK:mm a");
System.out.println(outputFormat.format(inputFormat.parse(input)));

Output:

Date : 25-04-2014
Time : 05:03 PM

Note the use of quoted sequences in the format, such a "'Date : '", which is treated as a literal within the format pattern.

I custom onTimeSet() function . Send the hour and minutes to it. It will return the time with format am and pm

public static String onTimeSet( int hour, int minute) {

    Calendar mCalen = Calendar.getInstance();;
       mCalen.set(Calendar.HOUR_OF_DAY, hour);
       mCalen.set(Calendar.MINUTE, minute);

       int hour12format_local = mCalen.get(Calendar.HOUR);
       int hourOfDay_local = mCalen.get(Calendar.HOUR_OF_DAY);
       int minute_local = mCalen.get(Calendar.MINUTE);
       int ampm = mCalen.get(Calendar.AM_PM);
       String minute1;
       if(minute_local<10){

        minute1="0"+minute_local;
       }
       else
          minute1=""+minute_local;

       String ampmStr = (ampm == 0) ? "AM" : "PM";
       // Set the Time String in Button

       if(hour12format_local==0)
        hour12format_local=12;



String selecteTime=hour12format_local+":"+ minute1+" "+ampmStr;

retrun selecteTime;


}
