我的问题是我不能排除小于当前日期的日期

当前日期为2015年11月11日至17日

以下是输出：

Answer 1

你已经从第一天开始循环
从当前日期开始

for (int x = 0; x < 4; x++) {
    for (int i = daynow; i < 31; i++) {
        if (i == day1) {
            System.out.println(df.format(setDateofMonth(yearnow, monthnow + x + 1, day1)));
        }
        if (i == day2) {
            System.out.println(df.format(setDateofMonth(yearnow, monthnow + x + 1, day2)));
        }
        if (i == day3) {
            System.out.println(df.format(setDateofMonth(yearnow, monthnow + x + 1, day3)));
        }
        if (i == day4) {
            System.out.println(df.format(setDateofMonth(yearnow, monthnow + x + 1, day4)));
        }
    }
}
