在Java中以d格式格式化day
Java日期中使用d格式来格式化日期，例如1、2、3、4等。让我们使用它。
// displaying day in d format
SimpleDateFormat simpleformat = new SimpleDateFormat("d");
String strDay = simpleformat.format(new Date());
System.out.println("Day in d format = "+strDay);上面，我们使用了SimpleDateFormat类，因此导入了以下包-
import java.text.SimpleDateFormat;
以下是一个例子-
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 {
// displaying current date and time
Calendar cal = Calendar.getInstance();
SimpleDateFormat simpleformat = new SimpleDateFormat("E, dd MMM yyyy HH:mm:ss Z");
System.out.println("Today's date and time = "+simpleformat.format(cal.getTime()));
// displaying date
simpleformat = new SimpleDateFormat("dd/MMMM/yyyy");
String str = simpleformat.format(new Date());
System.out.println("Current Date = "+str);
// displaying day in d format
simpleformat = new SimpleDateFormat("d");
String strDay = simpleformat.format(new Date());
System.out.println("Day in d format = "+strDay);
// current time
simpleformat = new SimpleDateFormat("HH.mm.ss");
String strTime = simpleformat.format(new Date());
System.out.println("Current Time = "+strTime);
}
}输出结果
Today's date and time = Mon, 26 Nov 2018 09:44:12 +0000 Current Date = 26/November/2018 Day in d format = 26 Current Time = 09.44.12
