Java中的SimpleDateFormat（“ hh：mm：ss a”）
以下格式显示时间从-
hh:mm:ss
以下格式使用AM/PM标记显示时间-
hh:mm:ss a
在这里，我们使用SimpleDateFormat类显示日期和时间。让我们将其设置为所需的格式，即时间和AM/PM标记-
Format f = new SimpleDateFormat("hh:mm:ss a");
String strResult = f.format(new Date());
System.out.println("Time = "+strResult);以下是一个例子-
示例
import java.text.Format;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Calendar;
public class Demo {
public static void main(String[] args) throws Exception {
//显示当前日期和时间
Calendar cal = Calendar.getInstance();
SimpleDateFormat simpleformat = new SimpleDateFormat("dd/MMMM/yyyy hh:mm:s zzzz");
System.out.println("Today's date = "+simpleformat.format(cal.getTime()));
//当前时间
Format f = new SimpleDateFormat("hh:mm:ss a");
String strResult = f.format(new Date());
System.out.println("Time = "+strResult);
//显示小时
f = new SimpleDateFormat("H");
String strHour = f.format(new Date());
System.out.println("Current Hour = "+strHour);
//显示分钟
f = new SimpleDateFormat("mm");
String strMinute = f.format(new Date());
System.out.println("Current Minutes = "+strMinute);
//显示秒
f = new SimpleDateFormat("ss");
String strSeconds = f.format(new Date());
System.out.println("Current Seconds = "+strSeconds);
}
}输出结果
Today's date = 26/November/2018 08:27:34 Coordinated Universal Time Time = 08:27:34 AM Current Hour = 8 Current Minutes = 27 Current Seconds = 34
