Summary: Learn how to efficiently handle date and time conversions in Java using DateFormat, a powerful utility for formatting and parsing date and time values.
---

Java provides robust tools for handling date and time operations, crucial for many applications ranging from basic utilities to complex enterprise systems. One such tool is the DateFormat class, which offers functionalities for formatting and parsing date and time values according to specific patterns.

What is DateFormat?

DateFormat is an abstract class in the java.text package, designed to format and parse dates and times. It's crucial for converting date and time values between their textual representations and Date objects, which are the core representation of date and time in Java.

Formatting Date and Time

To format a Date object into a human-readable string, you can utilize the DateFormat class. Here's a simple example:
