Converting 24-hour clock time to am/pm in Joda-Time
提问by Sam Haito
I just started working with Joda-Time, and got it to correctly display my date in 24-hour clock("military time") but I would rather it be am/pm. Looked it up and it mentioned hourOfDaywhich I figured was the HH value so I tried to write a loop that would break it down into AM/Pm but it never worked out.
我刚开始使用Joda-Time，并让它以24 小时制（“军用时间”）正确显示我的日期，但我宁愿它是 am/pm。查了一下，它提到了我认为是 HH 值的hourOfDay，所以我尝试编写一个循环，将其分解为 AM/Pm，但它从未奏效。
DateTime dtf = new DateTime(wikiParsedDate);
if (hourOfDay == 00) {
hourOfDay == 12;
DateTimeFormatter builder = DateTimeFormat.forPattern( "dd-MM-yyyy HH:mm:ss.SS'AM" );
return builder.print(dtf);
} else if (0 < hourOfDay && hourOfDay < 12) {
DateTimeFormatter builder = DateTimeFormat.forPattern( "dd-MM-yyyy HH:mm:ss.SS'AM" );
return builder.print(dtf);
} else if (hourOfDay > 12) {
hourOfDay - 12 == hourOfDay;
DateTimeFormatter builder = DateTimeFormat.forPattern( "dd-MM-yyyy HH:mm:ss.SS'PM" );
return builder.print(dtf);
}
}

Look at the API documentation of DateTimeFormat. This should do what you want:
查看DateTimeFormat. 这应该做你想做的：
DateTimeFormatter builder = DateTimeFormat.forPattern("dd-MM-yyyy hh:mm:ss.SSa");
No need for the complication with different cases.
不需要复杂的不同情况。
