将日期格式化为Java的星期格式 EEEE
EEEEE 格式用于 Java Date 以星期格式安排星期,如星期一、星期二、星期三等。我们使用它如下所示 −
// displaying day of week SimpleDateFormat simpleformat = new SimpleDateFormat("EEEE"); String strDayofWeek = simpleformat.format(new Date()); System.out.println("Day of Week = "+strDayofWeek);
上面,我们使用了 SimpleDateFormat 类,因此导入以下软件包 −
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); // displaying day of week simpleformat = new SimpleDateFormat("EEEE"); String strDayofWeek = simpleformat.format(new Date()); System.out.println("Day of Week = "+strDayofWeek); // current time simpleformat = new SimpleDateFormat("HH.mm.ss Z"); String strTime = simpleformat.format(new Date()); System.out.println("Current Time = "+strTime); } }
输出
Today's date and time = Mon, 26 Nov 2018 09:40:25 +0000 Current Date = 26/November/2018 Day of Week = Monday Current Time = 09.40.25 +0000
