java - To check time value in JSpinnerand set date in JDateChooser accordingly -

i have 2 jdatechooser(named firstdate , lastdate) , jspinner(named starttime , endtime) in gui.

the scenario is,

1.if open gui current time , set in endtime , currenttime-1 in starttime(the code below),

calendar cal = calendar.getinstance(); cal.add(calendar.hour, -1); date onehourback = cal.gettime(); string timestamp = new simpledateformat("hh:mm:ss").format(onehourback); date date = new simpledateformat("hh:mm:ss").parse(timestamp); starttime.setvalue(date); 

2.for both jdatechooser set current date.

3.if current time 00:44:36 (hh:mm:ss), in starttime(jspinner) have set 23:44:36, have set firstdate(jdatechooser) value previous day date instead of current date.

for trying following way,

calendar currenttime = calendar.getinstance(); date curhr = currenttime.gettime(); string curtime = new simpledateformat("hh").format(curhr); int timecheck = integer.parseint(curtime);  if(timecheck > 00 && timecheck < 01){  //code set previous day's    date                                        } 

is way it? or there better way available? please help

you should able use onehourback date value value lastdate jdatechooser, not has time been rolled back, has date value, example...

calendar cal = calendar.getinstance(); cal.set(calendar.hour_of_day, 0); cal.set(calendar.minute, 44); cal.set(calendar.second, 36);  date starttime = cal.gettime();  cal.add(calendar.hour, -1); date endtime = cal.gettime();  system.out.println("starttime = " + starttime); system.out.println("endtime = " + endtime); 

outputs...

starttime = thu feb 06 00:44:36 est 2014 endtime = wed feb 05 23:44:36 est 2014 

this nice thing calendar
