Java 中 d 格式设置日
d 格式用于 Java Date 中 1、2、3、4 等格式化日。让我们来使用它。
// 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,因此导入以下包 -
import java.text.SimpleDateFormat;
以下是一个示例 -
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
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
