在 Java 中显示三位数的年中的天数
使用 ‘j’ 日期转换字符显示年中的三位数天数。
System.out.printf("Three-digit Day of the Year: %tj/%Tj
", d, d);
上面,d 是个日期对象 −
Date d = new Date();
以下是示例 −
示例
import java.util.Date; import java.text.DateFormat; import java.text.SimpleDateFormat; public class Demo { public static void main(String[] args) throws Exception { Date d = new Date(); DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a"); String format = dateFormat.format(d); System.out.println("Current date and time = " + format); System.out.printf("Four-digit Year = %TY
",d); System.out.printf("Two-digit Year = %ty
",d); System.out.printf("Three-digit Day of the Year: %tj/%Tj
", d, d); } }
输出
Current date and time = 26/11/2018 12:13:14 PM Four-digit Year = 2018 Two-digit Year = 18 Three-digit Day of the Year: 330/330
