ตัวอย่าง
package demo.file;
import java.io.File;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class ChangeFileLastModifiedExample {
/**
* @param args
*/
public static void main(String[] args) {
try {
File file = new File("C:\\users\\nopphanan7\\newfile.txt");
// 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 newLastModified = "05/18/2014";
// need convert the above date to milliseconds in long value
Date newDate = sdf.parse(newLastModified);
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();
}
}
}
ผลลัพธ์ที่ได้คือ
Original Last Modified Date : 05/17/2014 Lastest Last Modified Date : 05/18/2014
