在 Java 中使用 SimpleDateFormat('yyyy') 来显示年份
使用 SimpleDateFormat(“yyyy”) 显示年份 −
// displaying year Format f = new SimpleDateFormat("yyyy"); String strYear = f.format(new Date()); System.out.println("Year = "+strYear);
由于我们已经使用了上面的 Format 和 SimpleDateFormat 类,因此需要导入以下程序包。除此之外,我们还使用了 Date −
import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;
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 Format f = new SimpleDateFormat("dd/MMMM/yyyy"); String strDate = f.format(new Date()); System.out.println("Current Date = "+strDate); // displaying year f = new SimpleDateFormat("yyyy"); String strYear = f.format(new Date()); System.out.println("Year = "+strYear); // current time f = new SimpleDateFormat("HH.mm.ss Z"); String strTime = f.format(new Date()); System.out.println("Current Time = "+strTime); // displaying hour f = new SimpleDateFormat("H"); String strHour = f.format(new Date()); System.out.println("Current Hour = "+strHour); // displaying minutes f = new SimpleDateFormat("mm"); String strMinute = f.format(new Date()); System.out.println("Current Minutes = "+strMinute); // displaying seconds f = new SimpleDateFormat("ss"); String strSeconds = f.format(new Date()); System.out.println("Current Seconds = "+strSeconds); } }
输出
Today's date and time = Mon, 26 Nov 2018 09:19:54 +0000 Current Date = 26/November/2018 Year = 2018 Current Time = 09.19.54 +0000 Current Hour = 9 Current Minutes = 19 Current Seconds = 54
