在Java中如何查找前2个星期一的日期？

您走在正确的轨道上。

Calendar cal = Calendar.getInstance();cal.add(Calendar.DAY_OF_YEAR, -7); // First week beforecal.add(Calendar.DAY_OF_YEAR, -7); // Second week before

让我仅在星期一进行这项工作。

Calendar cal = Calendar.getInstance();int weekday = cal.get(Calendar.DAY_OF_WEEK);int days = (Calendar.SATURDAY - weekday + 2) % 7;cal.add(Calendar.DAY_OF_YEAR, days);cal.add(Calendar.DAY_OF_MONTH, -7);cal.add(Calendar.DAY_OF_MONTH, -7);
