How to Retrieve a File\'s Creation Date in Java?

Determining File Creation Date in Java

Retrieving the creation date of a file can be crucial for various applications, such as sorting files chronologically. In this context, Java provides several mechanisms to access file metadata, including its creation date.

One promising option is through the Java New I/O (NIO) API. NIO allows you to interact with files and file systems in a platform-independent manner. As long as the underlying file system supports providing file creation metadata, NIO can access it.

Retrieving Creation Date Using Java NIO

For instance, using the BasicFileAttributes class in NIO, you can obtain various file attributes, including its creation time. The following code demonstrates this:

Path file = ...;
BasicFileAttributes attr = Files.readAttributes(file.toPath(), BasicFileAttributes.class);

System.out.println("creationTime: " + attr.creationTime());
System.out.println("lastAccessTime: " + attr.lastAccessTime());
System.out.println("lastModifiedTime: " + attr.lastModifiedTime());

Note: The availability of file creation date metadata might depend on the underlying file system and its configuration. Additionally, the format of the date retrieved can vary based on the file system implementation.
