Question

嗨，我的秒数如下

long seconds = 1299671538L;

使用上述秒数我想显示日期和时间（12小时格式）我编写的代码如下：

SimpleDateFormat formatter = new SimpleDateFormat(
                             "EEEE, MMMM d, yyyy HH:mm,a", Locale.getDefault());
String dateString = formatter.format(new Date(seconds * 1000L));
System.out.println(dateString);

我的输出为Wednesday, March 9, 2011 17:22,PM。

但我想显示Wednesday, March 9, 2011 05:22,PM(12 hour format)

Answer 1

使用hh代替HH。 SimpleDateFormat的文档描述了这一点。

Answer 2

使用hh代替HH 12小时格式。

SimpleDateFormat formatter = new SimpleDateFormat(
                    "EEEE, MMMM d, yyyy hh:mm,a", Locale.getDefault());
