How to Convert a Date String from yyyy-MM-dd HH:mm:ss to dd-MM-yyyy HH:mm:ss in Java

Handling date and time formatting in Java can sometimes be tricky, especially when converting between different string formats. In this post, we will explore how you can convert a date string formatted as yyyy-MM-dd HH:mm:ss to dd-MM-yyyy HH:mm:ss in Java and avoid common pitfalls, such as java.lang.IllegalArgumentException.

Steps to Convert Date Format

Parse the Input String:
First, you need to parse the input date string from the format yyyy-MM-dd HH:mm:ss into a Date object.

Format the Date:
Then, format the Date object into the desired date string format dd-MM-yyyy HH:mm:ss.

Here's a sample code snippet demonstrating these steps:

Handling Common Errors

java.lang.IllegalArgumentException: Cannot format given Object as a Date

This error often occurs when the input string cannot be parsed into a Date object due to an incorrect format. Ensure that the input string strictly follows the format specified in your SimpleDateFormat constructor.

Key Takeaways

Use SimpleDateFormat to define the input and output date formats.

Always wrap your parsing and formatting logic in a try-catch block to handle potential ParseExceptions gracefully.

Make sure that the date string you wish to parse aligns perfectly with the pattern defined in your SimpleDateFormat.

By following these steps and keeping these tips in mind, you can efficiently convert date strings between different formats in Java while avoiding common errors.
