How do I convert a java.util.Date from yyyy-mm-dd to mm-dd-yyyy format?

Converting java.util.Date Format from yyyy-mm-dd to mm-dd-yyyy

When working with dates in Java, you may need to convert between different date formats. One common conversion is from yyyy-mm-dd to mm-dd-yyyy. This can be achieved through the SimpleDateFormat class.

Understanding Date Objects
Date objects represent a specific point in time as the number of milliseconds since the Unix epoch (January 1, 1970). They do not have an inherent format.

SimpleDateFormat Class

The SimpleDateFormat class provides methods for formatting and parsing dates. To convert a date format, follow these steps:

  1. Create a SimpleDateFormat object with the desired format pattern:
<code class="java">SimpleDateFormat sm = new SimpleDateFormat("mm-dd-yyyy");</code>
Copy after login
  1. Format the Date object to a String using the formatter:
<code class="java">String strDate = sm.format(myDate);</code>
Copy after login
  1. (Optional) Parse the String back to a Date object (retains the original date value):
<code class="java">Date dt = sm.parse(strDate);</code>
Copy after login

Example Usage

<code class="java">Date myDate = new Date(); // Initialize a Date object

// Format myDate to mm-dd-yyyy
String formattedDate = new SimpleDateFormat("mm-dd-yyyy").format(myDate);

System.out.println("Original date: " + myDate);
System.out.println("Formatted date: " + formattedDate);</code>
Copy after login

Alternative Approach (Java 8 )

Java 8 introduced the new Date and Time API, which provides a more concise way to format dates using DateTimeFormatter:

<code class="java">LocalDateTime ldt = LocalDateTime.now();
String formattedDate = DateTimeFormatter.ofPattern("MM-dd-yyyy").format(ldt);</code>
Copy after login
