以 ss 格式(01、02)显示秒数在 Java 中
秒的 ss 表示法与表示秒 01、02、03、04 等类似。我们将其用作如下方式。
SimpleDateFormat("ss");
让我们看一个示例 -
// displaying seconds in ss format simpleformat = new SimpleDateFormat("ss"); String strSeconds = simpleformat.format(new Date()); System.out.println("Seconds in ss format = "+strSeconds);
在上面,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"); System.out.println("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); // current time simpleformat = new SimpleDateFormat("HH.mm.ss"); String strTime = simpleformat.format(new Date()); System.out.println("Current Time = "+strTime); // displaying seconds in ss format simpleformat = new SimpleDateFormat("ss"); String strSeconds = simpleformat.format(new Date()); System.out.println("Seconds in ss format = "+strSeconds); } }
输出
Date and time = Mon, 26 Nov 2018 10:53:04 Current Date = 26/November/2018 Current Time = 10.53.04 Seconds in ss format = 04
