Java 实现：输入年月日，轻松获取下一天日期

```java public String nextDay(int year, int month, int day) { if (month == 2) { if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)) { if (day < 29) { day++; } else { day = 1; month++; } } else { if (day < 28) { day++; } else { day = 1; month++; } } } else if (month == 4 || month == 6 || month == 9 || month == 11) { if (day < 30) { day++; } else { day = 1; month++; } } else { if (day < 31) { day++; } else { if (month == 12) { year++; month = 1; day = 1; } else { month++; day = 1; } } } return year + "-" + String.format("%02d", month) + "-" + String.format("%02d", day); } ``` ######[AI写代码神器 | 691点数解答 | 2024-10-13 16:49:47]
