Why Does Java Date() Return an Incorrect Date Format?

Java Date() Providing Incorrect Date Format

A user reported receiving an erroneous date of "2013-02-43" when attempting to retrieve the current date using Java's Date(). Investigating the issue, it was discovered that the code responsible for this conversion utilized an incorrect SimpleDateFormat pattern.

The issue stems from a misunderstanding of the pattern characters used in SimpleDateFormat. Specifically, the code incorrectly used "DD" instead of "dd" for the Day of Month, and "YYYY" instead of "yyyy" for the Year.

To rectify the error, the correct pattern "yyyy-MM-dd" should be employed. Here's the corrected code:

<code class="java">public String getDate() {
    DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
    Date date = new Date();

    return dateFormat.format(date);
}</code>

By using the correct pattern, the code will now accurately format the date as a String. Remember to pay attention to case sensitivity when specifying the pattern, as there are subtle differences between uppercase and lowercase letters.
