EEEEE格式在Java日期中用于格式化星期几,例如星期一,星期二,星期三等。让我们使用它-
//显示星期几 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,因此导入了以下包-
import java.text.SimpleDateFormat;
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("E, dd MMM yyyy HH:mm:ss Z"); System.out.println("Today's date and time = "+simpleformat.format(cal.getTime())); //显示日期 simpleformat = new SimpleDateFormat("dd/MMMM/yyyy"); String str = simpleformat.format(new Date()); System.out.println("Current Date = "+str); //显示星期几 simpleformat = new SimpleDateFormat("EEEE"); String strDayofWeek = simpleformat.format(new Date()); System.out.println("Day of Week = "+strDayofWeek); //当前时间 simpleformat = new SimpleDateFormat("HH.mm.ss Z"); String strTime = simpleformat.format(new Date()); System.out.println("Current Time = "+strTime); } }
输出结果
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
