在Java中使用SimpleDateFormat（“ M”）显示月份号
要显示月份号，请使用SimpleDateFormat（“M”）
//显示月份号
Format f = new SimpleDateFormat("M");
String strMonth = f.format(new Date());
System.out.println("Month Number = "+strMonth);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;
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 and time = "+simpleformat.format(cal.getTime()));
//显示日期
Format f = new SimpleDateFormat("dd/MMMM/yyyy");
String strDate = f.format(new Date());
System.out.println("Current Date = "+strDate);
//显示月份号
f = new SimpleDateFormat("M");
String strMonth = f.format(new Date());
System.out.println("Month Number = "+strMonth);
//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 09:16:16 Current Date = 26/November/2018 Month Number = 11 Current Time = 09.16.16 +0000 Current Hour = 9 Current Minutes = 16 Current Seconds = 16
