java - 我只想使用数组列表添加和打印 6 个项目

Question

如果今天是星期一，则其编号为 2。并且我需要将接下来的 5 个工作日添加到数组列表中，其中不应包括星期日(假日)。我是编码新手，正在学习第九标准。请帮助我编码。谢谢!

 public class WeekView {
 public static void main(String args[]) {
     List<Integer> daysList = new ArrayList<>();
     int m = 6, dayOfWeek = 6;
     for (int i = 1; i <= m; i++) {
         if (dayOfWeek == 1) {
             daysList.add(dayOfWeek);
             dayOfWeek++;
         } else if (dayOfWeek == 2) {
             daysList.add(dayOfWeek);
             dayOfWeek++;
         } else if (dayOfWeek == 3) {
             daysList.add(dayOfWeek);
             dayOfWeek++;
         } else if (dayOfWeek == 4) {
             daysList.add(dayOfWeek);
             dayOfWeek++;
         } else if (dayOfWeek == 5) {
             daysList.add(dayOfWeek);
             dayOfWeek++;
         } else if (dayOfWeek == 6) {
             daysList.add(dayOfWeek);
             for (int j = 1; j < dayOfWeek; j++) {
                 daysList.add(j);
             }
         }
     }
     System.out.println("Day Num :" + daysList);
 } }

我当前的输出是

Day Num :[6, 1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5]

但是我需要如下所示的输出

  6,1,2,3,4,5

Answer 1

List<Integer> daysList = new ArrayList<>();
int day = 6;

for (int i = 0; i < 6; i++) {
    daysList.add(day);
    day++;
    if(day > 6) day = 1;
}

System.out.println("Day Num :" + daysList);

地点:

• i 迭代工作日数
• daysList.add(day) 将当前日期添加到列表
• days++ 在每次循环迭代时转到第二天
• if(day > 6) day = 1 如果 day 到达星期日，则返回星期一
