I'm confused. It looks like your code will print in 24 hour format to me? It says here that HH represents the 24 hour format
我糊涂了。看起来您的代码将以 24 小时格式打印给我？这里说HH代表24小时制

HH is exactly what you need. It's 24 hour format. See SimpleDateFormat API. Change your computer time to 16:00 and try your code again to test.
HH 正是您所需要的。这是 24 小时制。请参阅 SimpleDateFormat API。将您的计算机时间更改为 16:00 并再次尝试您的代码以进行测试。
