JAVA 给过去一年每一天生成1个文件

 

获取一月中最大的天数：yearMonth.lengthOfMonth();

 public static void test002() throws IOException {
        // 定义年
        int year = 2024;
        String path ="C:\\Users\\computer\\Desktop\\2years\\"+year;
        // 定义12个月份
        for(int month=1;month<=12;month++){
            YearMonth yearMonth = YearMonth.of(year, month);
            // 获取一月中最大的天数
            int days = yearMonth.lengthOfMonth();

            String filename="";
            if(month<10){
                filename = filename+ "0"+month;
            }else {
                filename = filename+ month;
            }


            for(int i=1;i<=days;i++){
                String fileName002=filename;

                if(i<10){
                    fileName002 = fileName002+ "0"+i;
                }else {
                    fileName002 = fileName002+ i;
                }
                fileName002 +=".txt";
                // 创建文件并写入
                Files.write(Paths.get(path+fileName002),(path+fileName002).getBytes());
                System.out.println(path+fileName002);
            }
        }

    }
