以 hh(AM/PM 中的 01-12)格式显示 Java 中的时间
Java Date 中的“hh”格式类似于 AM/ PM 中的 01 – 12 小时。使用 SimpleDateFormat("hh") 获取相同的格式;
// displaying hour in hh format SimpleDateFormat simpleformat = new SimpleDateFormat("hh"); String strHour2 = simpleformat.format(new Date()); System.out.println("Hour in hh format = "+strHour2);
上面,我们使用了 SimpleDateFormat 类,因此导入以下包 −
import java.text.SimpleDateFormat;
以下是一个示例 −
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("E, dd MMM yyyy HH:mm:ss Z"); System.out.println("Today's date and time = "+simpleformat.format(cal.getTime())); // displaying date simpleformat = new SimpleDateFormat("dd/MMMM/yyyy"); String str = simpleformat.format(new Date()); System.out.println("Current Date = "+str); // current time simpleformat = new SimpleDateFormat("HH.mm.ss Z"); String strTime = simpleformat.format(new Date()); System.out.println("Current Time = "+strTime); // displaying hour in h format simpleformat = new SimpleDateFormat("h"); String strHour1 = simpleformat.format(new Date()); System.out.println("Hour in h format = "+strHour1); // displaying hour in hh format simpleformat = new SimpleDateFormat("hh"); String strHour2 = simpleformat.format(new Date()); System.out.println("Hour in hh format = "+strHour2); } }
输出
Today's date and time = Mon, 26 Nov 2018 09:54:57 +0000 Current Date = 26/November/2018 Current Time = 09.54.57 +0000 Hour in h format = 9 Hour in hh format = 09
