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“−”
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
