The last modification date can be accessed using the lastModified method from the File Object
long lastModified = file.lastModified();
Here is an example for getting the last modification Date of a file in Java.
The code first creates a File Object with the file path; then it calls the lastModified method to get the a long for the date. Finally, the long is used to create a date that is then formatted and printed in the output.
import java.io.File;
import java.text.SimpleDateFormat;
import java.util.Date;
public class FileLastModificationDate {
public static void main(String[] argv){
File file = new File( "V:/tmp/test.txt" );
long lastModified = file.lastModified();
String pattern = "yyyy-MM-dd hh:mm aa";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern);
Date lastModifiedDate = new Date( lastModified );
System.out.println( "The file " + file + " was last modified on " + simpleDateFormat.format( lastModifiedDate ) );
}
}
The file V:\tmp\test.txt was last modified on 2017-01-16 04:54 PM
