Adding second, minute, hour, day to java.util.date

long secondInMilis  = 1000;
long minuteInMilis  = secondInMilis * 60;
long hourInMilis  = minuteInMilis * 60;
long dayInMilis  = hourInMilis * 24;

Date add1Second = new Date(new Date().getTime() + secondInMilis);
Date add10Second = new Date(new Date().getTime() + (10 * secondInMilis));

Date add1Minute = new Date(new Date().getTime() + minuteInMilis);
Date add10Minute = new Date(new Date().getTime() + (10 * minuteInMilis));

Date add1Hour = new Date(new Date().getTime() + hourInMilis);
Date add10Hour = new Date(new Date().getTime() + (10 * hourInMilis));

Date add1Day = new Date(new Date().getTime() + dayInMilis);
Date add10Day = new Date(new Date().getTime() + (10 * dayInMilis));

Done!!
