How To Change The File Last Modified Date In Java?

 
Here’s an example to change the file’s last modified date with the help of File.setLastModified() . This method accept the new modified date in milliseconds (long type), So some data type conversion are required.

 

import java.io.File;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class ChangeFileLastModifiedDate {
	public static void main(String[] args) {

		try {

			File file = new File("C:\File.pdf");

			// Print the original last modified date
			SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
			System.out.println("Original Last Modified Date : "
					+ sdf.format(file.lastModified()));

			// Set this date

			String newFileDate = "11/17/2000";

			// Need convert the above date to milliseconds in long value
			Date newDate = sdf.parse(newFileDate);
			file.setLastModified(newDate.getTime());

			// Print the latest last modified date
			System.out.println("Lastest Last Modified Date : "
					+ sdf.format(file.lastModified()));

		} catch (ParseException e) {

			e.printStackTrace();

		}

	}
}

 

Result :

 
Original Last Modified Date : 12/20/2011
Lastest Last Modified Date : 11/17/2000
