Can any one tell me solution for the following: I have a Util.Date object in java.I want to validate the date entered. I am parsing the date object using the required format.

For ex, Format is "MM/dd/yyyy" and Date entered is "23/12/2010" For this date, I am not getting any Parse Exception but the date is adjusted to "11/12/2011" which should not happen in my case.Instead I want to throw error message.

请在这方面帮助我。

在日期,必须重新确定“放大”旗帜,即:

SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
sdf.setLenient(false);
. . .
sdf.parse(mydate, pos);

你们必须树立你的“宽容”模式,简单地说,For:

SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
sdf.setLenient(false);

否则会容忍某些错误,试图解释这些错误。

根据你的格式表述,我们可以使用简单格式调整月份、日期和年份,代码如下:

public class SimpleDateFormatString2DateParse {

public static void main(String[] args) {

    SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yyyy");

    try {
        Date date = formatter.parse("11/12/2011");
        System.out.println("Date is : " + date);

    } catch (Exception e) {
        e.printStackTrace();
    }

   }
   }
