How to Convert a Date Object from One Format to Another Using SimpleDateFormat?

Converting a Date Object from One Format to Another Using SimpleDateFormat#format

To convert a date object from one format to another without using deprecated classes, utilize the SimpleDateFormat#format method.

In the example provided, you attempted to parse and format a date using SimpleDateFormat. However, you encountered an issue because parse expects a String input, not a Date object.

To correctly convert the date, follow these steps:

  1. Create SimpleDateFormat objects for both the original and target date formats.
  2. Use originalFormat.parse to parse the date string into a Date object.
  3. Use targetFormat.format to format the Date object into the desired date string.

Here is the revised code:

DateFormat originalFormat = new SimpleDateFormat("MMMM dd, yyyy", Locale.ENGLISH);
DateFormat targetFormat = new SimpleDateFormat("yyyyMMdd");
Date date = originalFormat.parse("August 21, 2012");
String formattedDate = targetFormat.format(date);
