1. 求两个年月之间的月份,包含开始月份
/**
* @param startMonth @example: "2016-01"
* @param endMonth @example: "2019-11"
* @return 两个时间之间的月份(含开始,结束)
* @throws ParseException
*/
private List<String> getMonths(String startMonth,String endMonth) throws ParseException{
LinkedList<String> months = new LinkedList<>();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM");
Calendar minCalender = Calendar.getInstance();
Calendar maxCalender = Calendar.getInstance();
// 设置开始月份
minCalender.setTime(sdf.parse(startMonth));
minCalender.set(minCalender.get(Calendar.YEAR), minCalender.get(Calendar.MONTH),1);
maxCalender.setTime(sdf.parse(endMonth));
// 设置日期,保证最后一个日期参数 大于 开始时间日历
maxCalender.set(maxCalender.get(Calendar.YEAR), maxCalender.get(Calendar.MONTH),2);
while (minCalender.before(maxCalender)) {
months.add(sdf.format( minCalender.getTime() ));
minCalender.add(Calendar.MONTH, 1);
}
return months;
}
2. 求两个年月之间的月份,包含开始月份,不含结束月份
/**
* @param startMonth @example: "2016-01"
* @param endMonth @example: "2019-11"
* @return 两个时间之间的月份(含开始,不含结束)
* @throws ParseException
*/
private List<String> getMonths(String startMonth,String endMonth) throws ParseException{
LinkedList<String> months = new LinkedList<>();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM");
Calendar minCalender = Calendar.getInstance();
Calendar maxCalender = Calendar.getInstance();
// 设置开始月份
minCalender.setTime(sdf.parse(startMonth));
// 设置结束月份
maxCalender.setTime(sdf.parse(endMonth));
while (minCalender.before(maxCalender)) {
months.add(sdf.format( minCalender.getTime() ));
minCalender.add(Calendar.MONTH, 1);
}
return months;
}
