您可以使用SimpleDateFormat(“ a”)在Java中轻松显示AM / PM时间标记。
首先,要使用Java中的SimpleDateFormat类,请导入以下包。
import java.text.SimpleDateFormat;
现在,使用SimpleDateFormat(“ a”)设置格式以显示AM / PM标记-
Format f = new SimpleDateFormat(”a”);
现在,将标记放入字符串中-
String strMarker = f.format(new Date());
以下是一个例子-
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"); System.out.println("Today's date = "+simpleformat.format(cal.getTime())); //显示小时 Format 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); //以两位数显示秒 f = new SimpleDateFormat("ss"); String strSeconds = f.format(new Date()); System.out.println("Current Seconds = "+strSeconds); //显示AM / PM- f = new SimpleDateFormat("a"); String strMarker = f.format(new Date()); System.out.println("Current AM/PM Marker = "+strMarker); } }
输出结果
Today's date = 26/November/2018 08:08:52 Current Hour = 8 Current Minutes = 08 Current Seconds = 52 Current AM/PM Marker = AM
