用Java显示一年中的三位数日期
使用“j”日期转换字符来显示一年中的三位数。
System.out.printf("Three-digit Day of the Year: %tj/%Tj\n", d, d);上面的d是一个日期对象-
Date d = new Date();
以下是一个例子-
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\n",d);
System.out.printf("Two-digit Year = %ty\n",d);
System.out.printf("Three-digit Day of the Year: %tj/%Tj\n", d, d);
}
}输出结果
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
