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;
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
