This will work

    DateFormat df = new SimpleDateFormat("HH:mm:ss");
    Date date = new Date();
    System.out.println(df.format(date));
    long milSec=date.getTime();
    long addMilSec=123*60*1000;

    long sum=milSec+addMilSec;
    Date d=new Date(sum);

    System.out.println(df.format(d));

try like this

 Calendar now = Calendar.getInstance();
 now.setTime(YOUR_DATE_OBJECT);//pass your date here

 now.add(Calendar.MINUTE, 50);//add 5o minutes
 now.add(Calendar.SECOND, -50);// subtract 50 seconds

Create a GregorianCalendar object: http://docs.oracle.com/javase/7/docs/api/java/util/GregorianCalendar.html add you hours/minutes/whatever you need to add and then get back a Date

Create a Calendar object, instead of Date, and use add.

Example:

Calendar c = Calendar.getInstance();
c.add(Calendar.MINUTE, 123);
String s = sdf.format(c.getTime());
