请问我的代码有什么错误
java.text.ParseException: Unparseable date:"16-Jan-2014 10:25:00" (at offset 3)
提前感谢…您使用小写字母“m”已经有几个月了。它们应改为大写字母M。如下所述: 所以模式是这样的:
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy HH:mm:SS", Locale.ENGLISH);
你已经用了几个月的小写字母“m”。它们应改为大写字母M。如下所述: 所以模式是这样的:
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy HH:mm:SS", Locale.ENGLISH);
考虑下面的例子
String text = "2014-01-17T00:00:00.000-0500";
DateFormat sdf = new SimpleDateFormat("yyyy-MMM-dd'T'HH:mm:ss.SSSZ");
希望这有助于考虑以下示例
String text = "2014-01-17T00:00:00.000-0500";
DateFormat sdf = new SimpleDateFormat("yyyy-MMM-dd'T'HH:mm:ss.SSSZ");
希望这能有所帮助。正如@Tim Kranen所提到的,月份格式是大写的。所以它应该是MMM
为了理解月份格式,考虑这个短代码-< /P>
/*
Formatting month using SimpleDateFormat
This example shows how to format month using Java SimpleDateFormat class. Month can
be formatted in M, MM, MMM and MMMM formats.
*/
import java.text.SimpleDateFormat;
import java.util.Date;
public class FormattingMonth {
public static void main(String[] args) {
//create Date object
Date date = new Date();
//formatting month in M format like 1,2 etc
String strDateFormat = "M";
SimpleDateFormat sdf = new SimpleDateFormat(strDateFormat);
System.out.println("Current Month in M format : " + sdf.format(date));
//formatting Month in MM format like 01, 02 etc.
strDateFormat = "MM";
sdf = new SimpleDateFormat(strDateFormat);
System.out.println("Current Month in MM format : " + sdf.format(date));
//formatting Month in MMM format like Jan, Feb etc.
strDateFormat = "MMM";
sdf = new SimpleDateFormat(strDateFormat);
System.out.println("Current Month in MMM format : " + sdf.format(date));
//formatting Month in MMMM format like January, February etc.
strDateFormat = "MMMM";
sdf = new SimpleDateFormat(strDateFormat);
System.out.println("Current Month in MMMM format : " + sdf.format(date));
}
}
/*
Typical output would be
Current Month in M format : 2
Current Month in MM format : 02
Current Month in MMM format : Feb
Current Month in MMMM format : February

请用上述示例检查格式。如@Tim Kranen所述,月份格式为大写字母。所以它应该是MMM

请使用上面提到的示例检查,以了解格式。这行不通。你还需要三个M。两个MM将以这种格式解析日期:2014年1月16日。但是给定的格式有一个三个字符的月。这行不通。你还需要三个M。两个MM将以这种格式解析日期:2014年1月16日。但是给定的格式有三个字符的月份。
