Reading a File by Knowing a part of the file name

Question

Hi Java Gurus,
Can I copy a file to another location by knowing a part of the file name.I know the extension of the file and part of the file name.Can I copy such a file to another directory?
Eg :
0099999999_JAPPLIC_20090320.pdf is the file name.
I know the file name contains 'JAPPLIC' .Can I use this clue and the extension of the file to copy the file to another directory.
Please let me know whether it is possible or not.
Regards,
Rakesh.

Hi ,
I used the below code and I was able to solve the problem.I was able to select the files of the required extension and serach for the file names containing the text I know and use such files and move to another directory.It may be helpfulk to you people
public class FileDeletion {
public static void main (String args[]) {
     String e = "";
     String d = "C:\\TCCTouchpoints\\Attachments_Export\\outbound";
     String newFileLoc = "C:\\TCCTouchpoints\\Attachments_Export\\move";
ExtensionFilter filter = new ExtensionFilter(e);
File dir = new File(d);
File newLoc = null;
String[] list = dir.list(filter);
if (list.length == 0) return;
System.out.println("File Length "+list.length);
ArrayList fileNames = new ArrayList();
for (int i = 0; i < list.length; i++) {
/*file = new File(d + list);
boolean isdeleted = file.delete();
System.out.print(file);
System.out.println( " deleted " + isdeleted);*/
     System.out.println(list[i]);
     if(list[i].contains("_F5029.03_")){
          fileNames.add(list[i]);
          //System.out.println(list[i]);
dir = null;
for(int i=0;i<fileNames.size();i++){
     dir = new File(d+"\\"+fileNames.get(i));
     newLoc = new File(newFileLoc+"\\"+fileNames.get(i));
     if(dir.renameTo(newLoc)){
          System.out.println(dir + " is moved to "+ newLoc);
     }else {
          System.out.println("***** " dir " is not moved to "+ newLoc);
     dir = null; newLoc = null;
for(int i=0;i<list.length;i++){
     dir = new File(d+"\\"+list[i]);
     dir.delete();
class ExtensionFilter implements FilenameFilter {
private String extension;
public ExtensionFilter( String extension ) {
this.extension = extension;
public boolean accept(File dir, String name) {
return (name.endsWith(extension));
Thanks for replying .......
