How to subtract dates to get days/hrs/mins/secs when java does not allow su

final long MS_IN_A_DAY = 1000*60*60*24;

final long MS_IN_AN_HOUR = 1000*60*60;

final long MS_IN_A_MINUTE = 1000*60;

final long MS_IN_A_SECOND = 1000;

java.util.Date date1;

java.util.Date date2;

long diff = date1.getTime() - date2.getTime();

long numDays = diff/MS_IN_A_DAY;

diff = diff%MS_IN_A_DAY;

long numHours = diff/MS_IN_AN_HOUR;

diff = diff%MS_IN_AN_HOUR;

long numMinutes = diff/MS_IN_A_MINUTE;

diff = diff%MS_IN_A_MINUTE;

long numSeconds = diff/MS_IN_A_SECOND;

diff = diff%MS_IN_A_SECOND;

long numMilliseconds = diff;

String result = numDays + " days, " + numHours + " hours, " + numMinutes + " minutes, " + numSeconds + " seconds, " + numMilliseconds + " ms";
