Java程序获取全日名称
要显示全天名称，请使用SimpleDateFormat（“EEEE”），如下所示-
//显示全天名称
f = new SimpleDateFormat("EEEE");
String str = f.format(new Date());
System.out.println("Full Day Name = "+str);由于我们已经使用了上面的Format和SimpleDateFormat类，因此导入以下软件包。因此，我们也使用了日期。
import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;
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("dd/MMMM/yyyy hh:mm:s");
System.out.println("Today's date = "+simpleformat.format(cal.getTime()));
//当前时间
Format f = new SimpleDateFormat("HH.mm.ss Z");
String strResult = f.format(new Date());
System.out.println("Time = "+strResult);
//显示两位数的日期
f = new SimpleDateFormat("dd");
String strDay = f.format(new Date());
System.out.println("Day Number = "+strDay);
//显示全天名称
f = new SimpleDateFormat("EEEE");
String str = f.format(new Date());
System.out.println("Full Day Name = "+str);
//显示小时
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);
//显示秒
f = new SimpleDateFormat("ss");
String strSeconds = f.format(new Date());
System.out.println("Current Seconds = "+strSeconds);
}
}输出结果
Today's date = 26/November/2018 09:06:49 Time = 09.06.49 +0000 Day Number = 26 Full Day Name = Monday Current Hour = 9 Current Minutes = 06 Current Seconds = 49
