Rename a file which is most recently downloaded through selenium and Java

Sometimes We need to rename a file which is most recently downloaded through selenium or which is most recent in a directory(folder). Here is a solution that will work for you.


package fileRename;

import java.io.File;
import java.io.FileFilter;
import java.io.IOException;
import java.util.Arrays;
import org.apache.commons.io.comparator.LastModifiedFileComparator;
import org.apache.commons.io.filefilter.WildcardFileFilter;

public class FileRename {

public static void main(String[] args) throws IOException {

FileRename fr= new FileRename();
File newfile = fr.getTheNewestFile("F://downloads", "zip");
newfile.renameTo(new File("F://downloads//Suchandra Karle.zip"));
String filename= newfile.getName();

System.out.println("latest file is="+filename);

FileRename fr1= new FileRename();
File updated = fr1.getTheNewestFile("F://downloads", "zip");
System.out.println("Changed file name is ="+updated);

    }

public File getTheNewestFile(String filePath, String ext) {
   File theNewestFile = null;
   File dir = new File(filePath);
   FileFilter fileFilter = new WildcardFileFilter("*." + ext);
   File[] files = dir.listFiles(fileFilter);

   if (files.length > 0) {
       /** The newest file comes first **/
       Arrays.sort(files, LastModifiedFileComparator.LASTMODIFIED_REVERSE);
       theNewestFile = files[0];
   }

   return theNewestFile;
}
}
