How to Convert Dates Without Using Deprecated `SimpleDateFormat` Classes?

Date Conversion Without Deprecated Classes

You may encounter the need to convert a date from one format to another. However, the SimpleDateFormat class offers deprecated methods. How can we achieve this conversion without using these deprecated classes?

Solution: Employ the SimpleDateFormat#format method

To convert a date without using deprecated classes, follow these steps:

• Create two SimpleDateFormat instances: originalFormat for the initial date format and targetFormat for the desired format.
• Use originalFormat.parse(originalDateString) to parse the initial date string and obtain a Date object.
• Apply targetFormat.format(date) to the Date object to obtain the converted date in the desired format.

Example:

Consider the following sample 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);  // 20120821

In this example, we parse the date "August 21, 2012" in the "MMMM dd, yyyy" format and convert it to the "yyyyMMdd" format, resulting in "20120821".

Note: Remember that SimpleDateFormat#parse takes a String as input, not a Date object.
