格式SimpleDateFormat(“ HH.mm.ss”)显示时间。为了使用SimpleDateFormat类,我们导入了以下程序包。
import java.text.SimpleDateFormat;
在这里,我们使用SimpleDateFormat类显示日期和时间。让我们将其设置为所需的格式,即时间-HH.mm.ss-
Format f = new SimpleDateFormat("HH.mm.ss");
String strResult = f.format(new Date());
System.out.println("Time = "+strResult);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("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");
String strResult = f.format(new Date());
System.out.println("Time = "+strResult);
//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 08:32:16 Time = 08.32.16 Current Hour = 8 Current Minutes = 32 Current Seconds = 16
