让我们看看如何使用SimpleDateFormat('MM / dd / yy')格式化日期
//显示日期 Format f = new SimpleDateFormat("MM/dd/yy"); String strDate = f.format(new Date()); System.out.println("Current Date = "+strDate);
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。这样,我们还使用了日期。
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 and time = "+simpleformat.format(cal.getTime())); //显示日期 Format f = new SimpleDateFormat("MM/dd/yy"); String strDate = f.format(new Date()); System.out.println("Current Date = "+strDate); //当前时间 f = new SimpleDateFormat("HH.mm.ss Z"); String strTime = f.format(new Date()); System.out.println("Current Time = "+strTime); //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 and time = 26/November/2018 09:11:7 Current Date = 11/26/18 Current Time = 09.11.07 +0000 Current Hour = 9 Current Minutes = 11 Current Seconds = 07
