LocalDateTime获取年月日

要获取LocalDateTime的年月日，可以使用format方法和DateTimeFormatter类来进行格式化。具体的代码如下所示：

LocalDateTime localDateTime = LocalDateTime.now();
String formattedDate = localDateTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd"));
System.out.println("当前日期为：" + formattedDate);

这段代码将会输出当前的年月日，格式为"yyyy-MM-dd"，例如"2022-01-01"。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
