Old code but thought this would be useful

package com.ml;

import java.io.File;
import java.io.FilenameFilter;

public class FileFilterTest {

public static void main(String[] args) {

FilenameFilter filter=new FilenameFilter(){
public boolean accept(File dir, String fileName) {
return fileName.endsWith("java");
}
};

File f=new File("D:/Programs/Code");
String [] fileList=f.list(filter);
for (int i=0;i<fileList.length;i++){
System.out.println(fileList[i]);
}
}

}
