Java 中的 SimpleDateFormat(“hh:mm:ss a”)


以下格式显示时间“−”

hh:mm:ss

以下格式显示带 AM/PM 标记的时间“−”

hh:mm:ss a

这里,我们使用 SimpleDateFormat 类显示日期和时间。让我们将它设置成我们想要的格式,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);

下面是一个示例“−”

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 {
      // displaying current date and time
      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()));
      // current time
      Format f = new SimpleDateFormat("hh:mm:ss a");
      String strResult = f.format(new Date());
      System.out.println("Time = "+strResult);
      // displaying hour
      f = new SimpleDateFormat("H");
      String strHour = f.format(new Date());
      System.out.println("Current Hour = "+strHour);
      // displaying minutes
      f = new SimpleDateFormat("mm");
      String strMinute = f.format(new Date());
      System.out.println("Current Minutes = "+strMinute);
      // displaying seconds
      f = new SimpleDateFormat("ss");
      String strSeconds = f.format(new Date());
      System.out.println("Current Seconds = "+strSeconds);
   }
}

输出

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
