两个日期之间的开始日期和结束日期

Question

嗨，我需要获取给定之间每个月的所有开始日期和结束日期 两年

pulbic void printStartDateAndEndDate(Date start, Date end){

    for(// start - end){
      Sysout("1 st month starting date: "+ startDateOfMonth+ " End Date"+endDateOfMonth);    
    }

}

如果有人知道怎么做，请告诉我。我需要“startDateOfMonth”和“endDateOfMonth”在 Date 对象中。

使用JodaTime...

LocalDate startDate = new LocalDate(2011, 11, 8);
LocalDate endDate = new LocalDate(2012, 5, 1);

startDate = startDate.withDayOfMonth(1);

while (!startDate.isAfter(endDate)) {
    System.out.println("> " + startDate);
    startDate = startDate.plusMonths(1);
    LocalDate endOfMonth = startDate.minusDays(1);
    System.out.println("< " + endOfMonth);
}

使用 Java 8 的 time API

LocalDate startDate = LocalDate.of(2011, 11, 8);
LocalDate endDate = LocalDate.of(2012, 5, 1);

startDate = startDate.withDayOfMonth(1);

while (!startDate.isAfter(endDate)) {
    System.out.println("> " + startDate);
    startDate = startDate.plusMonths(1);
    LocalDate endOfMonth = startDate.minusDays(1);
    System.out.println("< " + endOfMonth);
}
