无法解析java中的日期年份

Question

我有一个MM/dd/yy格式的日期.我是从XML文件中获取的.比方说,比方说,就是这样10/03/11.

我在其上执行以下代码:

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");
}

输出是:

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

我似乎无法得到它10/03/2011.有什么想法吗？

当你解析的日期有两个字符的年份时,你simpleDateFormatter也应该yy只.

编辑:

// 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));
