无法解析java中的日期年份

Question

I have a date that is in the MM/dd/yy format. I get it from an XML file. Let's say, for example, it's 10/03/11 .

I execute the following code on it:

try {
    SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
    System.out.println("dateStr: " + dateStr);
    date = sdf.parse(dateStr);
    System.out.println("dateStr After: " + sdf.format(date));
} catch(Exception e) {
    System.out.println("Error when formatting date");
}

The output is:

dateStr: 10/03/11
dateStr After: 10/03/0011

I can not seem to get it to be 10/03/2011 . Any ideas why?

Answer 1

When the date you are parsing has year with two chars, your simpleDateFormatter should also yy only.

EDIT:

// First convert to date object
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yy");
System.out.println("dateStr: " + dateStr);

Date date = sdf.parse(dateStr);

SimpleDateFormat sdf2 = new SimpleDateFormat("MM/dd/yyyy");
sdf2.format(date);

// Then, format it to get 2011 with another date format.
System.out.println("dateStr After: " + sdf.format(date));
System.out.println("dateStr NEXT After: " +  sdf2.format(date));

It's a parse exception... Use MM/dd/yy instead of MM/dd/yyyy .

Like:

SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yy");
