Increment date by 1 & loop until end of the month
i hav String date & i want to开发者_开发知识库 inceament date by 1 & it should be loop until end of the month. as examle, if i take November 2010 it should loop 30 days. if i take December 2010 it should loop 31 days. below shows my code......
String date="12/01/2010";
String incDate;
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
Calendar c = Calendar.getInstance();
c.setTime(sdf.parse(date));
for(int co=0; co<30; co++){
c.add(Calendar.DATE, 1);
incDate = sdf.format(c.getTime());
}
String date="12/01/2010";
String incDate;
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
Calendar c = Calendar.getInstance();
c.setTime(sdf.parse(date));
int maxDay = c.getActualMaximum(Calendar.DAY_OF_MONTH);
for(int co=0; co<maxDay; co++){
c.add(Calendar.DATE, 1);
incDate = sdf.format(c.getTime());
}
The c.getActualMaximum(Calendar.DAY_OF_MONTH)
result will be the last day of the month.
Another solution could be:
String date = "01/11/2010";
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Calendar c = Calendar.getInstance();
try {
c.setTime(sdf.parse(date));
} catch (ParseException ex) {
Logger.getLogger(DateIterator.class.getName()).log(Level.SEVERE, null, ex);
}
int maxDay = c.getActualMaximum(Calendar.DAY_OF_MONTH);
for (int co = 0; co < maxDay; co++) {
System.out.println(sdf.format(c.getTime()));
c.add(Calendar.DATE, 1);
}
