我有字符串日期 & 我想将日期增加 1 & 它应该循环到月底。例如，如果我选择 2010 年 11 月，它应该循环 30 天。如果我选择 2010 年 12 月，它应该循环 31 天。下面显示了我的代码......
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.
该c.getActualMaximum(Calendar.DAY_OF_MONTH)结果将是这个月的最后一天。

Another solution could be:
另一种解决方案可能是：
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);
}
