用Java的EEEE格式格式化星期几
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-
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 {
//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 +0000Current Date = 26/November/2018
Day of Week = Monday
Current Time = 09.40.25 +0000
